Approximation for elastic-plastic stressed notches including thermal induced stresses

Structural-mechanical loadings differ significantly from thermal and therefore displacement controlled loadings. This fact is becomes apparent when conventional notch approximation procedures are applicable under thermal loadings. Within the scope of this paper, a procedure is presented, how to calculate elastic-plastic notch stresses approximately, based on fictitiously elastic calculations, which are induced by thermal loading. Furthermore it will be shown, how the locally elastic-plastic partial solutions for the mechanical and the thermal loading can be combined and what influence it takes on the quality of the results.
