โฆ Synopsis
Stress intensity
factors were determined for very short edge cracks with different inclinations but equal depths of crack tips from the heated edge of a plate under transient thermal stresses. The critical orientation of edge cracks was found experimentally.

The boundary element method is applied to determine thermal stress intensity factors for a cusp crack in a transient state. In the steady temperature field, numerical values of thermal stress intensity factors for a Griffith crack and a symmetric lip cusp crack in a finite body are in good agreement
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
