On uniqueness and dilatational waves in a porous Cosserat thermoelastic body

Abstract In this paper first we formulate the mixed problem with initial and boundary values in the context of the porous Cosserat thermoelastic bodies micropolar material with voids. WE have included among the independent constitutive variables the derivative with respect to time of the voids (pores) function. Under the conditions in which we imposed average restrictions on the functions used, we formulated and demonstrated the uniqueness of the solution to the mentioned mixed problem and we did a short analysis on the dilatational waves in this kind of media.
