The elastic-plastic stress analysis of a centre-cracked plate subjected to two types of loading is considered using the non-linear BERSAFE finite element system. The loading includes both uniaxial tension and a quadratic thermal gradient across the plate, both of which independently would tend to op

โฆ Synopsis
Ah&r&-The problem of a centre-cracked plate of finite crack length to plate width ratio when subjected to a quadratic thermal gradient is studied. Stress intensity factors are derived from elastic analysis using an analytical approach and the finite element method. The apalytical approach is exact only for an infinitely wide plate so that the finite element results enable the evaluation of finite width correction factors. Various techniques for evaluating the stress intensity factor under thermal loading are reviewed, and the preferred ones are applied to the present problem. The resulting finite width correction factors are compared to those derived for the tensile Mode I loading case.
