Description
Summary:In this paper on the mathematical model of a multiphase medium (with longitudinally transverse arrangement of phases) and the algorithm for calculating strength under combined thermomechanical loading the method is proposed for analyzing the limiting state of a composite, which allows one to take into account the internal structure of the material and the anisotropy of the elastic and thermal properties of substructural elements. For each element of the composition the strength condition of P. P. Balandin is used. It takes into account various limits of tensile strength and compression of phase materials. A numerical study of condition of initial destruction of composites and its various sections in space of parameters of the external action under isothermal loading in the case of plane stressed state is made.
