Synopsis
The behaviour of polycrystalIine materials is modelled by means of elastic-plastic trusses. Including kinematic hardening already simple statically non-determined trusses simulate effects well known as LCF. Beside the accumulation of residual stress during cyclic loading we observe for large deformation of the trusses cyclic hardening and softening with “abrupt” softening simulating “failure by crack”.
