Abstract:

The objective of the present paper is the formulation of the general frame of an internal variable theory of high strain rate deformations in metals. Such deformation are characterized by nucleation, growth and coalescence of various microdefects like shear bands, cracks and voids. Localized deformations in the vicinity of these microdefects as well as disloaction motion in the remaining parts of the body contribute to the inelastic strain rate. After identification of appropriate internal variables through an approximate homogenization procedure, evolution laws and flow rules are introduced and investigated with respect to their consistency with thermodynamics. The Clausius-Duhem inequality is utilized as a measure of irreversibility. Introducing a polynomial representation of specific free enthalpy, thermodynamically consistent evolution laws are derived. Finally, the theory is applied to the problem of propagation of uniaxial acceleration waves into an unstressed homogeneous medium.
