00925njm 22002777a 4500 dc Gesto Beiroa, José Manuel author Gens Solé, Antonio author Vaunat, Jean author 2011 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 weell-known cases. Moreover, we show that a multi-surface plasticity model can be reduced to a model ith a single yield surface by using the same smoothing procedure.
