ON STRESS EVALUATION IN THE LAMCAL CODE
The theoretical background of the stress routine in the LAMCAL code is described. This routine is based on small strains and uses a Von Mises yield function with a combined isotropic - kinematic hardening rule. Three methods to evaluate the stresses and plastic strains are implemented: tangent radial return, radial return and the secant method. All three methods can be used in a substepping way. Plastic recovery is allowed if numerical unloading is detected.
