摘要

The thermoelastic potential of displacements and Airy stress function are used to determine stresses in infinite and semiinfinite planes with circular thermal inclusions (whose coefficients of linear thermal expansion differ from the corresponding coefficients of the matrix) subjected to uniform heating. The stress concentration is investigated in the case where inclusions are located near the boundary of the half plane. Analytic expressions are deduced for the stress intensity factors in the vicinity of a rectilinear crack located between two identical inclusions.
