Autoři :HALAMA, R., MARKOPOULOS, A., SEDLÁK, J.
Abstrakt :This paper points out a sufficient description of the stress-strain behavior of the Chaboche kinematic hardening model only for materials with the Masing's behavior, regardless of the number of backstress components. Subsequently there are presented two concepts of most widely used memory surfaces: Jiang-Sehitoglu concept (stress-space model) and Chaboche concept (strain-space). On the experimental data of steel ST52 is then shown the possibility of capturing hysteresis loops in the usual range for low cycle fatigue calculations.
