摘要: Plastic constitutive laws and frictional contact conditions induce strong nonlinearities that one has to take into account in the numerical simulation of material forming processes. In this work, we present a review different techniques which permit asymptotic method (ANM) be adapted these nonlinearities. ANM needs regular relations quadratic equations if possible. Several examples show effectiveness proposed method.
