Abstract (EN):
The present work intends to evaluate, using simple, exemplary cases, the importance of a full elasto-plastic analysis in fatigue design. A strain cycling situation (-epsilon to epsilon) was modelled with ABAQUS considering two situations: firstly a linear sigma vs. epsilon relationship was assumed, and secondly, the real cyclic sigma vs. epsilon curve was used to model each cycle, which includes a small plastic deformation. The case of change of cross section in a steel shaft subjected to constant torsion and cyclic bending was analysed through finite element modelling using ABAQUS.
