About instability in an elastic Cosserat body with pores

Abstract This article is centered on the study of the isotropic, porous Cosserat elastic media, realized by means of a parallel with the media of the same type, but anisotropic, by following the rewriting in a new form of the equations that govern this theory, respectively the equations of motion and the equation of equilibrated forces balance, dependent only on the displacements, respectively on the volume fraction, correlated to the pores, useful for future practical implementations.
