Abstract

Numerical simulation of the microscopic damage progress in type IV creep failure of low alloy steel welds was carried out. A combination of elastic-creep finite element analysis and random fracture resistance modeling was used for the analysis. The fracture resistance of the grain boundary, stress-dependent initiation and growth driving forces of small defects were determined.
