摘要：

The investigation characterizes the mixed mode I-mode III fracture resistance of steel, similar to ASTM A710 Grade A, of composition 0. 04% C, 0. 04% Nb, 1. 17% Cu, 0. 90% Ni, 0. 70% Cr, 0. 49% Mn, 0. 27% Si, 0. 20% Mo, 0. 007% N, 0. 010% P, 0. 009% S, balance Fe. Plates were heat treated to two schedules to produce a ferritic structure containing either peak aged or overaged Cu precipitates. A linear relation between externally applied J components can be predicted by imposing a local fracture criterion at the crack tip and modeling the plastic zone ahead of the crack by two superdislocations.
