摘要：
In this paper, Kantowski-Sach's cosmological model is investigated in presence of Saez-Ballester scalar tensor theory of gravitation and an anisotropic dark matter distribution the energy momentum tensor. Exact solutions of field equations are obtained by the law of Hubble parameter. An anisotropic stellar object's stability is discussed with the help of sound speed, Aberu's stability condition, and causality condition. In addition to this, we studied the physical aspects of the derived cosmological model, such as transverse and radial pressure, energy density, and anisotropy factor etc.
