Abstract—This paper presents a one-dimension kinematic hardening model based on continuous hyperplasticity with infinite number of yield surface. Continuous hyperplasticity is a development of hyperplasticity theory, an approach to plasticity theory based on thermodynamics principles. It gives ability to develop many sophisticated engineering models that can describe more realistic behavior. In order to apply to numerical analysis, the discretization from infinite number of yield surface to multiple-yield-surface is shown. Applications to 1-D Finite element model using rate-dependent solution will be mentioned in this paper. The results show that this is a promising theory that can be describe nonlinear elasto-plastic response of material. By a suitable choice of some parameters, realistic behavior of a model can be derive.

Index Terms—multiple-yield-surface, rate-dependent, cyclic loading, kinematic hardening, thermodynamic, elasto-plastic.
