Abstract:An approach to modeling creep fracture under a complex stress state using the Finite Element Method is proposed. The model of the turbine blade root was studied. The methodology of the transition in the analysis from the general 3D to the 2D stress state is proposed. For the models of the roots, the characteristics of the damage accumulation were obtained and the analysis of subsequent fracture in roots made of different materials was performed.The novel results of the description the creep fracture behavior a… Show more
