โœฆ Synopsis

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 element (FE) method. Once the thermal problem is solved, SIFs at various time steps are calculated for numerous crack arrays (2-1024) and for a wide range of crack lengths. The present results emphasize the considerable influence of the above factors on the prevailing SIFs at the tips of these cracks.

The paper considers the axisymmetric problem of a circular edge crack on the inner surface of a long thick-walled cylinder constituted with an ideally elastic-plastic material. The walls of the cylinder are assumed to be stress free. Under axial loading, it is assumed that the plastic zone is a thin
