Abstract: Cyclic viscoplastic constitutive equations are increasingly used for the inelastic analysis of structures under severe thermomechanical conditions. The purpose of the paper is to show how the ...

Abstract: The cyclic constitutive equations developed at ONERA have been incorporated into a general thermodynamic framework (Part I). In the present part, systematic comparisons are given between the model ...

Abstract: Continuum Damage Mechanics (CDM) allows the description of the influence of damage on the stress-strain behavior of materials. In the present part, some practical damage growth equations are ...

Abstract: Continuum Damage Mechanics (C.D.M.) has developed continuously since the early works of Kachanov and Rabotnov. It constitutes a practical tool to take into account the various damaging processes ...

Abstract: The modeling possibilities of several linear and nonlinear-kinematic hardening rules are studied in detail in the particular case of tension-compression and in the framework of time-independent ...

Abstract: This paper deals with the monotonic and cyclic behavior of austenitic stainless steels and the way to model it. Developments made on constitutive equations led to elaborate sophisticated models ...

Abstract: The constitutive modeling of cyclic plasticity has made great progress during the past twenty years. One of the incompletely solved problems concerns ratchetting, that is the progressive strain ...

Abstract: The constitutive equations developed in Part I with a combination of isotropic and nonlinear kinematic hardening rules can describe the usual monotonic and cyclic behavior of metals and alloys. ...

Abstract: The description of monotonic and cyclic behavior of material is possible by generalizing the internal stress concept by means of a set of internal variables. In this paper the classical isotropic ...
