Notes:
This paper presents the development of a new boundary element formulationfor analysis of fracture problems in creeping materials. For the creep crack analysis the DualBoundary Element Method (DBEM), which contains two independent integral equations, wasformulated. The implementation of creep strain in the formulation is achieved through domainintegrals in both boundary integral equations. The domain, where the creep phenomena takesplace, is discretized into quadratic quadrilateral continuous and discontinuous cells. The creepanalysis is applied to metals with secondary creep behaviour. This is con…ned to standard powerlaw creep equations. Constant applied loads are used to demonstrate time e¤ects. Numericalresults are compared with solutions obtained from the Finite Element Method (FEM) andothers reported in the literature
