A targeted example is the case of a geometrically exact model of highly flexible slender structure, that includes, after space discretisation, trigonometric non-linear terms. With a suitable change of variables, this system can be rewritten in an equivalent one with polynomial non-linearities at most quadratic, at the price of introducing additional variables linked to algebraic equations, leading to a differential algebraic set of equations (DAE) to be solved. This DAE is reduced thanks to a normal form parametrisation of its invariant manifolds and selecting a set of master ones. Arbitrary order expansions are detailed for the coefficients of the change of variable and the reduced dynamics, using linear algebra in the space of multivariate polynomials of a given degree. In the case of a single non-linear mode reduction, a criterion to evaluate the quality of the normal form results is also proposed based on an estimation of the convergence radius of the polynomial asymptotic expansion representing truncated series. The method is then applied to compute a single mode reduction of three test cases – a Duffing oscillator, a simple pendulum and a clamped clamped beam with von Kármán model –, in order to investigate the effect of the algebraic part of the DAE on the quality of the model reduction and its validity range. Then, the more involved case of a cantilever beam modelled by geometrically exact finite elements is considered, underlining the ability of the method to produce accurate and converged results in a range of amplitude that can be bounded thanks to a convergence criterion.</div></div>","PeriodicalId":50303,"journal":{"name":"International Journal of Non-Linear Mechanics","volume":"178 ","pages":"Article 105138"},"PeriodicalIF":2.8,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144204484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modified Johnson-Cook model and microstructural based model were further modified to enhance the prediction accuracy. The prediction accuracy of the proposed constitutive equations was appraised by the determination coefficient and the average absolute relative error, which are 0.9680 and 14.05 % for the modified Johnson-Cook model, 0.9773 and 9.58 % for the strain compensated Arrhenius-type model, 0.9961 and 6.53 % for the modified Zerilli-Armstrong model and 0.9948 and 4.53 % for the microstructural based model, respectively.

We study traffic flow’s linear and nonlinear stability, focusing on the impact of interruption probability on the phase diagram, both theoretically and numerically.

A change from smooth flow to kink flow and sometimes chaotic flow as the risk of an interruption goes up in the stable zone. At lower values of the non-interruption effect, there is a typical jamming transition between uniform flow and kink flow.

These joints experience complex flight loads, leading to nonlinear deformation and strain behaviors due to the contact and friction mechanisms at the joint interfaces. To gain a deeper understanding of the nonlinear mechanical behavior of such joints, this study conducts static tension and compression tests, complemented by nonlinear finite element simulations. Initially, typical radial countersunk screw lap joint specimens are fabricated and tested under tension and compression loads using an MTS universal testing machine. A preliminary analysis of the load-deformation relationship is performed based on the experimental data. Subsequently, a numerical model is developed using the nonlinear finite element method. This model is validated against experimental results and utilized to predict the evolution of contact behavior and the distribution of stress/strain within the specimens. Furthermore, a parametric analysis is conducted to investigate the influence of key design parameters on the joint's mechanical behavior. The findings indicate that the nonlinear mechanical behavior primarily stems from changes in the contact state between different components, while the differences in tensile and compressive behaviors are driven by variations in contact stiffness. Additionally, the size of the screw-hole clearance and assembly clearance significantly impacts the slip behavior observed in the load-displacement curves. Variations in screw preload and lap length have an important effect on the initial stiffness of the joint. These insights provide a foundation for optimizing the design and performance of radial countersunk screw lap joints for aerospace applications.</div></div>","PeriodicalId":50303,"journal":{"name":"International Journal of Non-Linear Mechanics","volume":"177 ","pages":"Article 105159"},"PeriodicalIF":2.8,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
