Often such assessments involve finite element simulation of the components; thus it is essential to include residual stress fields in the model. While previous methods have been proposed to include residual stresses in finite element models (e.g. using iterative methods or eigenstrain reconstruction of residual stresses), these can be theoretically cumbersome and computationally expensive. In this work a novel technique for reconstruction of residual stresses in welds is presented, based on iterative stress imposition and relaxation, and using limited residual stress data from energy dispersive X-ray diffraction (EDXD) measurements. This method is validated using a combination of neutron imaging of small sections of the weld and finite element analysis. A root mean squared (RMS) error of 127.26 <span><math><mrow><mi>μ</mi><mi>ɛ</mi></mrow></math></span> was achieved between the FE model and the EDXD measurement. Although the method is only viable for relatively simple geometries such as pipes and plates, this covers the most likely use cases in relevant industries such as nuclear energy. Reconstruction of residual stress fields can assist structural integrity assessments by requiring less measured residual stress data. As well as reducing measurement costs our method may enable less overly-conservative assessments, particularly for flaws that do not lie on a weld centreline. This work also demonstrates that neutron imaging residual strain measurement is a valuable tool for validating methods of weld residual stress modelling.</div></div>","PeriodicalId":56287,"journal":{"name":"International Journal of Mechanical Sciences","volume":"285 ","pages":"Article 109803"},"PeriodicalIF":7.1,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed model was validated by comparing it with the measured temperature and deformation. Results show a transforming distribution of interface temperature from a M-shape to a squished V-shape during the IFW process. The characterization is attributed to the transformation of the accumulated friction energy density at the interface from a M-shape to an approximate V-shape due to the combined effect of varying sliding velocity and contact pressure. The Mises stress at the region near the interface is high and low at the steel and Al alloy sides, respectively. A significant portion of the kinetic energy stored in the flywheel is dissipated in the form of plastic deformation energy and cannot be neglected.

Furthermore, a new experimental setup achieves precisely simply supported boundary conditions, and scaled physical models of two- and three-span bridge plates are employed to validate the analytical solution. The effect of span length mismatch is studied by analyzing the resonant frequencies and mode shapes of a multi-span bridge plate with varying span lengths.

However, the roles of tension, twist, and geometry in determining the buckling modes of a stretched ribbon under torsion remain unclear. In this study, we comprehensively investigate the torsional instabilities of elastic ribbons through experiments, theory, and finite element simulations. A one-dimensional model is employed to describe the nonlinear torsional responses in the helicoid stage. We present a modeling approach to describe the crease configuration and derive a semi-analytical solution based on the finite element analysis. We find that the competition between the macroscopic and microscopic buckling modes is governed by the thickness-to-width ratio, which determines the relative magnitudes of the membrane and bending strain energy in the helicoid. Additionally, as the applied tension increases, the buckling mode shifts from the longitudinal to the transverse direction. A three-dimensional phase diagram, as a function of twist, tension, and thickness-to-width ratio, is constructed to identify the morphology transitions of elastic ribbons.

Therefore, it is necessary to investigate the effect of surface integrity on quality factor of HSR. This work focuses on the surface integrity evolution of fused silica HSR machined by the multi-energy field coupled magnetorheological polishing (MEMRP) and the influence of surface integrity on quality factor. Firstly, the mechanism of removing subsurface damage and surface morphology evolution of the fused silica component machined by MEMRP were investigated to reveal the surface quality evolution rules. It was found that the removal of subsurface damage in fused silica components can be divided into three zones: rapid improvement zone, slow improvement zone, and gentle improvement zone. The improvement of surface roughness is slow in the gentle improvement zone, and the nonlinear regression model between subsurface damage depth and surface roughness is proposed. Then, the surface structure evolution and the mechanical characteristics of the surface layer of fused silica components during the MEMRP process was systematically analyzed. It was found that the initial polishing stage significantly improved the surface mechanical performance parameters. Finally, the quality factor of HSR with various surface qualities was measured. The results show that the subsurface damage depth and quality factor exhibit nonlinear relationship and the crack surface layer has a significant impact on the quality factor. Completely removing the subsurface damage, quality factor of HSR with diameter of 20 mm increased from hundreds of thousands to 2.01×10⁷, and the uniformity of quality factor is 1.2 %.

Mechanical performance, self-recovery under large deformations, reusable, and strain rate-dependent adaptive energy absorption are achieved. Furthermore, the mechanical performance and functionality of the semi-closed structure composed of both plates and curved shell (SPCS) are further enhanced by filling shear thickening gel (STG).

The extrusions resulting from spatial constraints between the axisymmetric shell containers and the STG fillers enhance strength and plateau stress, improve impact resistance, and enable adaptive energy absorption. The variation in stiffness and energy absorption of filled-SPCS with strain rate adeptly resolves the conflict between comfort and functionality in designs such as wearable protective devices, blast protection, and reactive armor, thereby paving the way for the development of strain rate-dependent mechanical metamaterials.
