Abstract

The method of Singular Integral Relations (SIR) for solving problems of stationary thermoelasticity for a piecewise homogeneous transversely isotropic space is generalized. Using the SIR method, the stationary thermoelasticity problem for interphase circular inclusion that is in smooth contact with piecewise homogeneous transversely isotropic space is reduced directly to a system of two-dimensional singular integral equations (SIE) with nuclei, which are expressed through elementary functions. An exact solution has been built for the said SIS; as a result, dependences of the translational displacement of the inclusion on temperature, the resulting load, the main momentum and the thermomechanical characteristics of transversely isotropic materials have been obtained. The order of the features of stresses and displacements jump is determined. Expressions for the stress intensity factor at the boundary of the inclusion are obtained, as well as numerical dependences of these coefficients on the polar angle, temperature and loads.
