Micropolar theory of solid subjected to initial stress

Abstract

The basic of the initial stress in an elastic continuum is revisited, then this investigation studies micropolar elastic solid subjected to initial stress using the classical method. The strain energy density function was developed to derive the constitutive relations and field equations when the influence of initial stress is taken into account. The case of linear-homogeneous isotropic and anisotropic condition of field and constitutive relations of the solid is obtained.
