“…This model allows one to take into account kinematic and isotropic hardening for transient and stabilized cyclic plasticity, and is provided from version (5.6) in the ABAQUS code. The von Mises yield criterion has been used in these computations, though for some materials with a high hardening effect, this criterion might be not sufficient 17 . As a matter of fact the Chaboche model 10 is modelling the Bauschinger effect through a displacement of the centre of the von Mises yield surface.…”

“…As a matter of fact the Chaboche model 10 is modelling the Bauschinger effect through a displacement of the centre of the von Mises yield surface. However, some materials 17 are found experimentally to display an additional distortion of the yield surface due to the hardening. Crystal plasticity models are more appropriate to describe such behaviour 18 .…”

The effect of overloads, underloads and stress ratio on plasticity‐induced crack opening level is examined for different ‘model’ materials. This study is focused on the consequences of the Bauschinger effect on the crack opening level. Various finite element analyses were conducted using ABAQUS to test these effects, involving the Chaboche constitutive equations that take into account both the Bauschinger effect of the material and its cyclic hardening or softening. The cyclic plastic behaviour of the material is found to strongly affect the crack behaviour after an overload or an underload. The experimental data obtained on a 0.4% carbon mild steel confirm the numerical results.
