โœฆ Synopsis

intensity factors were calculated at the deepest point and at the surface points of longitudinal semi-elliptical surface cracks in a thermally shocked pipe. The method of calculation is based on weight functions following a proposal by Mattheck, Munz and Stamm, Engng. Fract. Mech. 18, 633-641 (1983). Numerical values of the stress intensity factors are given for a wide range of crack depths and crack lengths considering a pipe with a wall-thickness to inner radius ratio of I/10. ' (2) n=l J$(anRi) -J?(anRa) 1 K is the coefficient of the heat diffusion equation, a the coefficient of thermal expansion, and the eigenvalvues a, are given by the equation J~(unRa) Yo(unRi) -Jo(anRi) Y~(anRa) = 0.

By means of the weight functions method stress intensity factors were calculated for axial semi-elliptical surface cracks in a pipe with cladding. The component is loaded by a thermoshock. Starting from a stress-free state the inner surface of the cladding is suddenly cooled down. The time-dependent
