Smoothing of yield surfaces and a reformulation of multi-surface plasticity Gesto Beiroa, José Manuel Gens Solé, Antonio Vaunat, Jean Àrees temàtiques de la UPC::Matemàtiques i estadística::Anàlisi numèrica::Mètodes en elements finits Finite element method Plasticity -- Mathematical models Plasticity Corners, Yield Surfcae, Plastic Potrntial, Muti-surface plasticity Elements finits, Mètode dels Plasticitat -- Models matemàtics Plasticitat 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. 2011 Conference report Open Access CIMNE
