Abstract

Temperature and stress distributions in a hollow sphere are calculated, caused by a sudden cooling (thermal shock) of the inner surface of a hollow sphere. The thermal stresses are acting as load of surface cracks of approximate semi‐elliptic shape. By means of the weight functions method stress intensity factors are estimated at the deepest point of the cracks using the well‐known Newman‐Raju solution for semi‐elliptical surface cracks in a plate as reference solution.

The line spring model with arbitrary distributed loads on crack surfaces is used to obtain the approximate solution for a surface-cracked plate subjected to thermal shock. The general formulation is finally reduced to two integral equations for net ligament stress and moment. Assuming that inertia e
