Modelling nonlinear phenomena in thin rubber shells calls for stretch-based material models, such as the Ogden model which conveniently utilizes eigenvalues of deformation tensor. Derivation and implementation models have been already made Finite Element Methods. This is, however, still lacking shell formulations based on Isogeometric Analysis, where higher-order continuity spline basis is empl...

Weakly nonlinear waves in elastic rods have been studied by many authors. Most studies concentrated on smooth solutions only. However, when waves are of moderate length, non-smooth waves, such as peakons (or solitary shock waves), can arise (see Dai and Huo 2000). For strongly nonlinear waves (not assuming the smallness of the wave amplitude), as far as the authors are aware, only incompressibl...

The inverse finite element method is a technique that can be used for material model parameter characterization. literature shows this approach may get caught in the local minima of design space. These minimum solutions often fit test data with small errors and are mistaken optimal solution. problem these sub-optimal becomes apparent when applied to different loading conditions where significan...

In this paper, nonlinear analytical solution of pressurized thick cylindrical shells with variable thickness made of hyperelastic materials is presented. The governing equilibrium equations for the cylindrical shell with variable thickness under non-uniform internal pressure are derived based on first-order shear deformation theory (FSDT). The shell is assumed to be made of isotropic and homoge...

This paper aimed to investigate the cornering characteristics of a Regional Haul Steer II, RHS 315/80 R22.5 truck tire traveling on dry, hard surface using Finite element analysis (FEA). research was carried out commercial Element software and Pam-Crash in an Explicit Environment. A finite model developed apply terrain condition. The concentrated loads boundary conditions for rim wheel were app...

The sealing system, as the most important load-bearing component, is a critical part of stack assembly in proton exchange membrane fuel cell (PEMFC). Currently, flat or single-peak gaskets are commonly used for large metal bipolar plate sealing, which can easily cause problems such significant internal stress and distortion displacement. In order to solve this problem, an innovative double-peak...
