Finite Element Analysis of Creep Crack Growth Based on Anisotropic Creep Damage Theory
An anisotropic creep damage theory is applied to analyse a crack propagation problem typical of the fracture mechanics. The process of crack growth initiated from an internal crack due to the anisotropic creep damage under proportional and non-proportional loadings is numerically calculated by the finite element method. The effect of damage anisotropy on the creep crack extension and the final rupture time is discussed by contrast with the numerical results based on an isotropic damage theory.
