Existing studies primarily focus on the flight characteristics of dandelion seed during its fall, emphasizing the influence of the complex filament structure on the formation of wake vortices. However, research on the flight lift force due to the dandelion seed’s morphological profile under lateral crosswind conditions is quite limited. This study investigates the aerodynamic behavior of dandelion seed using a novel virtual barrier model. This model is proposed, based on the regular pattern of the filaments’ outer contours and the virtual barrier effect produced by their columnar array. Through elaborate numerical simulations, it is found that the morphological profile of dandelion seed possesses superior aerodynamic properties, particularly in generating lift force under crosswind conditions. This characteristic is a crucial mechanism for the long-distance dispersal of dandelion seed. Subsequently, the study extends to examine the aerodynamic performance of the model at varying degrees of opening angles and inflow attack angles, offering a fresh perspective on understanding the flight characteristics of dandelion seed in natural environments. The findings not only contribute to the field of plant aerodynamics but also provide insights into potential biomimetic applications in engineering.</p></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"41 12","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During such test, accurate and comprehensive wing deformation measurement is crucial for assessing its strength, stiffness, and bearing capability. This paper proposes a novel and cost-effective videogrammetric method using multi-camera system to achieve the non-contact, high-precision, and 3D measurement of overall static deformation for the large-scale wing structure. To overcome the difficulties of making, carrying, and employing the large 2D or 3D target for calibrating the cameras with large field of view, a flexible stereo cameras calibration method combining 1D target and epipolar geometry is proposed. The global calibration method, aided by a total station, is employed to unify the 3D data obtained from various binocular subsystems. A series of static load tests using a 10-meter-long large-scale wing have been conducted to validate the proposed system and methods. Furthermore, the proposed method was applied to the practical wing deformation measurement of both wings with a wingspan of 33.6 m in the full-size civil aircraft static test. The overall 3D profile and displacement data of the tested wing under various loads can be accurately obtained. The maximum error of distance and displacement measurement is less than 4.5 mm within the measurement range of 35 m in all load cases. These results demonstrate that the proposed method achieves effective, high-accuracy, on-site, and visualized wing deformation measurement, making it a promising approach for full-scale aircraft wing static test.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"41 6","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the morphing process, the complex deformation of the flexible skin wing usually involves large amounts of movement, shearing, bending, and distortion. This paper proposes an improved stereo-digital image correlation measurement system designed to characterize full-field complex large deformation of flexible skin shear variable-sweep wings (SVSWs). By minimizing reference image updating frequency using the proposed conditional incremental strategy, effectively addressing the computational failures caused by image decorrelation due to complex large deformations. To improve tracking efficiency and accuracy of uncoded targets in complex backgrounds, an automatic subpixel detection method for circular diagonal targets is presented. A series of experiments are performed on a 1200 mm span flexible skin SVSW to verify the proposed methods. The results show that the length and angle measurement accuracies are better than 0.11 mm and 0.05°, respectively. Based on the measured morphing geometry parameters, displacement and strain fields, the structural integrity and morphing performance of the wing under different loads are discussed. During the shear variable-sweep process, the wingtip load dominates the deflection distribution, while its effect on the strain distribution is relatively minor.

The focus of this paper falls on the question: when the initially elliptical inclusion verges on a bi-material interface, what would happen to its configuration if it is required to retain the internal constant stress? Specifically, we explore the anti-plane shear version of this question (the version of plane deformations or three-dimensional deformations seems, however, insoluble at this stage), in which an inclusion undergoing a uniform (anti-plane shear) eigenstrain is embedded in a bi-material structure composed of two infinite elastic half-planes whose interface is straight and perfectly bonded, and the shape of the inclusion is to be determined such that the eigenstrain-induced stress inside the inclusion appears to be a constant. Unlike most optimization methods-driven solution procedures for finding the shape of the inclusion approximately in which huge computation is required, we derive by a rigorous theoretical analysis an exact integral equation with respect to the boundary curve of the inclusion that is sufficiently and necessarily related to the existence of a constant stress inside the inclusion. We solve this integral equation via the use of some analytic techniques and present in several illustrative examples a variety of shapes of the inclusion achieving constant stresses.

However, yaw angle tolerances always affect the accuracy of the results. To analyze this effect, this study conducted numerical simulations and theoretical derivations of non-ideal plate impacts. By comparing the simulated results of spallation, shock wave propagation, and free surface velocity, laws governing the effect of yaw angle on the plate impact were summarized. We observed that yaw angles influence the wave-action time and the shape of the compression zone, which affects the trigger and location of spallation and the free surface velocity of the target. Additionally, the yaw angle diminishes the kinetic energy of the target. When the yaw angle exceeds 2°, a significant energy reduction occurs as the shock wave propagates, which results in insufficient energy for complete spallation. Our analyses led to proposing methods for determining the critical yaw angle in plate impact experiments and to introducing a multipoint-velocimetry approach to calculate the non-ideal impact posture of the flyer. Notably, the findings revealed that 0.2° could serve as the critical yaw angle in certain scenarios.

However, research on the stability of detonation waves in complex reactive systems that are composed of actual fuels and oxidants and can be described by numerous elementary chemical reactions, has not been fully carried out. To investigate the relationship between linear and nonlinear stabilities in gaseous detonation wave propagation for complex reactive systems, the linear stability analysis and the one-dimensionally nonlinear numerical simulations of H₂/O₂/Ar (argon) detonations based on the reactive Euler equations and detailed reaction mechanisms are carried out. The results show that in complex reactive systems characterized by elementary chemical reactions, the results of linear stability computation of detonation are consistent with those from one-dimensionally nonlinear oscillations of detonation wave. Utilizing these linear stability results, a neutral stability curve and a perturbation frequency transition curve in the phase plane of initial pressure versus inert gas (Ar) dilution ratio are derived, especially the new frequency transition curve clearly describes the transition of perturbations from low-frequency to high-frequency mode. One-dimensional nonlinear simulations show that near the perturbation frequency transition curve, the oscillations of the detonation wave can also transform between the low-frequency, high-amplitude oscillation mode and the high-frequency, low-amplitude oscillation mode, with the oscillation frequency corresponding to the mode that exhibits the maximum growth rate identified in the linear stability analysis.

However, at the mesoscale, under shock wave impact, there is a notable scarcity of research on the deformation, temperature rise patterns, and heat transfer mechanisms of particle clouds. Most studies focus on loading methods such as drop hammer and falling tests. In our study, we introduce a particle motion elastoplastic contact model based on the discrete element method, enabling precise analysis of particle motion and collision behavior. Furthermore, we consider bidirectional coupling between the particle and gas phases, optimizing momentum and energy equations for the particle phase. This approach allows for a detailed analysis of the dynamics and thermodynamics between particles, systematically considering the elastoplastic collision and shear history between particles. Friction, rolling resistance, plastic dissipation, inter-particle heat transfer, and heat transfer between particles and the fluid are regarded as source terms in the energy equation. In this investigation, the deformation behavior and temperature rise process of particle clouds under shock wave impacts are thoroughly discussed. The temporal evolution of particle cloud temperature under shock wave impacts represents a spatiotemporal correlation phenomenon, delineated into two stages: accelerated temperature rise and steady temperature rise, resulting in the formation of symmetric critical high-temperature regions near the cavity perpendicular to the incoming shock wave direction. Notably, during the accelerated temperature rise stage, plastic dissipation, and two-phase heat transfer jointly contribute, whereas during the steady temperature increase stage, heat is primarily provided by two-phase heat transfer. Sustained heat transfer from the high-temperature shock-impacted gas phase to the particle phase acts as the primary mechanism triggering the formation of wide-range high-temperature regions. The role of plastic dissipation is mainly evident in the plastic collisions of particles near the cavity in the early stages. Additionally, we analyze the influence of incoming shock wave Mach numbers on temperature evolution and hot region formation patterns: stronger shock waves lead to quicker completion of the impact process and higher stable average temperatures. Under shock wave impact, the spatiotemporal characteristics of particle clouds differ from the results of the falling process. Prolonged two-phase heat transfer and intense plastic contact among particles near the cavity in the initial stages are factors triggering critical high-temperature regions.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"41 6","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influences of NS stress components on the mechanical response of DP steels are studied, including stress/strain partitioning, plastic flow, and yield surface. To this end, the mechanical behavior of the two phases is described by dislocation density-based crystal plasticity constitutive models, with the NS effect only incorporated into the ferrite phase modeling. The NS stress contribution is revealed for two types of microstructures commonly observed in DP steels: equiaxed phases with random grain orientations, and elongated phases with preferred grain orientations. Our results show that, in the case of a microstructure with equiaxed phases, the normal NS stress components play significant roles in tension-compression asymmetry.
