Abstract: Exact and variational methods of analysis are proposed which reduce a general elastic wave-propagation problem to a static problem plus an eigenvalue problem. The methods are shown to be ...

Abstract: In this paper a number of issues are addressed. The proper measure of intrinsic time is shown to be the norm of the increment of the plastic strain tensor, if the memory path is a line ...

Abstract: It is well known that wave equation in materials that suffer damage in the course of deformation loses it hyperbolicity when the damage process is described by a continuum damage theory of ...

Abstract: The initial value problem in finite “softening” material domains is discussed. An inequality that is true of all materials irrespective of their constitution is first established. It is then ...

Abstract: The paper is concerned with the theoretical prediction of cyclic hardening and cyclic softening of metals under conditions of cyclic straining. First, a constitutive equation of a hereditary ...

Abstract: This paper is concerned with a perturbation technique suitable for the stress analysis of viscoelastic solids with temperature-dependent properties in the presence of nonuniform transient temperature ...

Abstract: In this paper we present an analytical cum-numerical scheme, based on endochronic plasticity and the finite element formalism. The scheme is used to calculate the stress and elastoplastic strain ...

Abstract: In this paper we have used the endochronic theory of plasticity to model one of the most complex phenomena of mechanical behavior of materials, that of cyclic creep and relaxation. We have ...

Abstract: Integral constitutive equations of the endochronic type with only two easily determined material constants are shown to predict with computational ease the stress (plastic strain) response of ...
