Abstract:
Considering the difficulty of creep analysis of the three-dimensional cracks by the common numerical methods, this paper proposes a creep line-spring method (CLSM) for the estimates of creep fracture parameters for the creep surface cracks. The fundamental equations of the creep line-spring method are established on the bases of the approximate solutions of the non-steady creep crack and the elastic-plastic line-spring method. Several numerical examples for the creep fracture parameters, J and C integrals, ...
