Abstract
The onset of intergranular creep failure in polycrystalline metals is often identified with cavity coalescence on grain boundary facets normal to the maximum principal stress direction. Here, the additional effect of cavitation and grain boundary sliding on adjacent inclined boundaries is investigated. An axisymmetric model problem is used to study the combined influence of these failure processes. In creep constrained conditions, the interaction between both cavitation processes may significantly enhance cavity growth on the transverse grain boundary facets.
