✦ Synopsis
We report a simple method for a quick and efficient localization of thermal shock cracks as narrow as 1 µm or less, using Environmental Scanning Electron Microscopy (ESEM). The non-destructive character of the technique is exploited in order to observe relevant fractographic features of the crack pattern.

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
Transient mode I stress intensity factors (SIFs) resulting from a thermal shock for large arrays of up to 1024 radial cracks emanating from the inner surface of a thick-walled cylinder are evaluated. The transient thermal analysis as well as the computation of the SIFs is performed via the finite el
## 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 meth
