Dear all,
I have a problem now:
I simulated indentation on a elastic-plastic model with a rigid
indenter, the elastic ideal plastic with von mises stress model in
ABAQUS is used. A contact pair is applied to calculate the contact between the indenter and the sample.
The problem is that the obtained the force-displacement data in the loading part, which contains the plastic deformation
is not smooth, but in the unloading part is smooth. But if a model
without plastic is used, the force-displacement data is smooth.
