![]() ![]() If the deformation of a bar in tension becomes significant, its cross-sectional area will change. The strain output depends on the material model and the choice of small or large strain formulation.įor non-linear elastic models: von Mises Plasticity, Tresca Plasticity,ĭrucker Prager, Super Elastic, and Viscoelastic the small strain option produces engineering strains the large strain option produces logarithmic strains. After the analysis completes, the stress output is the Cauchy stress, which is the true stress in the deformed geometry.
