Abstract
A two-dimensional problem of two collinear cracks influenced by concentrated heat sources is studied. The considerations are limited to a problem of normal opening of the crack (Mode I) assuming that cracks of different lengths are thermally insulated and free of loads. The formulas describing displacements and stresses at any point of the body are given. The stress intensity factors at the crack tips and the openings of the cracks are obtained. To avoid possible overlapping of the cracks boundaries, the position of the heat sources and the lengths of the cracks are analyzed to ensure non-negative stress intensities factors (SIF's) at all the crack tips. The solution to the above problem has been derived using the method given by Panasuyk et al. [V.V. Panasuyk, M.P. Savruk, A.P. Datshshyn, Stress Distribution around Cracks in Plates and Shells, Naukova Dumka, Kiev, 1976 (in Russian); V.V. Panasuyk, M.P. Savruk, A.P. Datsyshyn, A general method of solution of two-dimensional problems in the theory of cracks, Eng. Fracture Mech. 9 (1977) 481–497.
