| Popis: | The behaviour of structural elements subjected to cyclic loading conditions is described by overlay models and simulated using standard finite element programs. The material model is established by parallel connection of several finite elements, each describing elasto-plastic material behaviour with kinematic or isotropic hardening and sharing the same geometrical position. The death or birth option, respectively, is used to simulate the yielding condition with a higher and lower yielding stress. A method estimating the material parameters is discussed. Results found by using ADINA 6.0 for the analysis of a cylindrical structural element under cyclic axial tension are presented. The effect of locally varying material parameters is discussed. |
