Finite element analysis of creep crack growth by local approach.

The applicability of a local approach to the analysis of creep crack growth in a plate is discussed from the view point of continuum damage mechanics. The anisotropic creep damage theory developed by the present authors is implemented into the finite element analysis based on two-dimensional simplex elements and the creep damage process leading to the initiation and propagation of creep cracks in a thin plate with an inner crack under...
