Smoothing of yield surfaces and a reformulation of multi-surface plasticity
Smoothing of yield surfaces and a reformulation of multi-surface plasticity
In this work we describe a procedure for the smoothing of non-regular yield surfaces and plastic potential functions. We also present several application examples corresponding to different well-known cases. Moreover, we show that a multi-surface plasticity model can be reduced to a model with a single yield surface by using the same smoothing procedure.
