Abstract

In the present paper computational applications are illustrated with reference to elasto/viscoplastic problems. The influence of differentloading programs on the inelastic behaviour of rate-sensitive elasto/viscoplastic materials is illustrated with specific numerical examples. An associated formulation of the evolutive laws is adopted. Differentloading procedures are taken into account by considering different values of the loadingrates and of the intrinsic properties of the material. A suitable integration scheme is applied and a numerical example is considered by analysing differentloading programs. Numerical computations and results are reported which illustrate the rate-dependency of the constitutive model in use. Consequently the significance of the loading program is emphasized with reference to the non-linear response of rate-dependent elasto/viscoplastic materials
