| Abstract | Hyperplasticity is an approach to plasticity theory based on thermodynamic principles. By using this concept, the entire constitutive model behaviour can be determined from two scalar functions, one is the energy function and the other is the yield function or the dissipation function. In this paper, the Hyperplasticity approach is described and implemented in finite element method (FEM) to solve a particular problem in structure analysis, the behaviour of a cantilever beam. The Gibbs free energy function and the Von Mises yield function are chosen to derive the elasto-plastic response of structures. Besides, kinematic hardening with single yield surface model are also presented and applied to describe the translation from elastic region to plastic region. The results show that the application of Hyperplasticity to FEM can be another proper way for non-linear analysis. Moreover, it reveals the ability to develop more sophisticated models using multiple yield surfaces in cases of cyclic loadings. |
