Plastic Spring CAEmate

Project Description

This Finite Element Analysis shows the residual stresses and the residual plastic deformation in a steel spring tended beyond its yield strength and then unloaded. The simulation was carried out while taking into account the geometrical non-linearities (large deformations). The material features are those of steel 50CrV4 (EN 10277), modeled according to Von Mises plasticity with linear hardening.
