Abstract
This paper presents a procedure for analyzing crack-tip regions of creeping, cracked structural components using the strain energy density rate concept and boundary element methodology. The investigated structural components are considered to undergo time-dependent, two-dimensional creep deformation and to be subjected to remote loading conditions while theirs deformation is assumed to be described by the elastic power law creep model. Some special boundary elements were used to simulate the time-dependent singular behavior of stress and strain fields at the crack tip of the investigated creeping materials. The strain energy density rate theory is applied to determine the direction of the crack initiation for a center cracked plate in tension which is subjected to Mode I loading conditions.
