摘要:

In a fracture analysis at elevated temperature, the determination of fracture parameter C* under steady-state creep is a crucial point. This paper proposes a rate-dependent energy release rate 6, by analogy with the definition of creep fracture parameter C* under steady-state creep. The relationship between <(G)over dot> and C* is deduced after a brief review of the definitions of parameters in fracture mechanics. Aimed at calculating <(G)over dot> and C*, a finite element formulation based on the virtual crack closure technique (VCCT) is established, which is called the extended VCCT in this paper. The numerical algorithm for this proposed formulation is presented and implemented into commercial finite element codes. The results obtained by the proposed numerical method are compared with those by finite element contour integral method and from different engineering estimation methods for SENT, MT and CT specimens. Good agreements of the C* results show that the extended VCCT is a reliable and efficient numerical method to calculate C* under steady-state creep.
