  • Theoretical analysis is carried out on relationship between crack arrest toughness Kca, crack arrest temperature TK and crack arrest stress σca in temperature-gradient double tension crack arrest test.Results indicate that there is a linear relation between crack arrest toughness Kca and crack arrest stress σca, while the linear coefficient is determined by specimen width Ws, temperature field parameters (T150 and GT) and crack arrest temperature TK. Statistical analysis of 21 groups of test data confirms the validation of this relationship.
