“…[23][24][25][26][27] The J-T zu -A T concept connects the advantages of the J-T zu and J-A 2 solutions; the J-T zu-A T solution is developed for the 3D crack-tip constraint theory. 28 To characterize two types of constraints, the following parameters of the plastic deformation behavior of the material near the crack tip can be also introduced in the model, 16,[29][30][31] the crack tip opening displacement, [32][33][34] the critical crack tip opening angle, 35 and the plastic work-based parameter. 36 At the same time, a discussion of the limitations of the plane strain two-parameter fracture mechanics approaches is cited in this paper so that readers can understand the reason why so many approaches were proposed.…”

The present paper deals with the J‐A concept in two‐parameter elastic–plastic approaches of fracture mechanics. The cumulative damage rule in a solid is employed to construct the quantitative elastic–plastic J‐A fracture criterion. As a result, the constraint corrected elastic–plastic fracture toughness as a function of the crack‐tip constraint parameter A, the yield stress, the strain hardening exponent and the failure stress has been proposed. The significant effect of the strain hardening exponent on the normalized constraint corrected fracture toughness is observed. The value of the normalized constraint corrected fracture toughness decreases with the increase of the applied failure stress and the decrease of the crack aspect ratio to a certain values, and then it stabilizes.

“…The advantages of A d * mainly include its capability of characterizing both constraints and its independences on load, material properties, and strength mismatch. These advantages facilitate developing A d * solutions for cracked structures (including welded structures), establishing the correlation between fracture properties of materials and A d *, and engineering application of A d * 40,41,50,51 . By using Equation (4), the A d * value can be calculated.…”

In this work, the correlation between ductile fracture toughness and a new unified constraint parameter A d * for bi-material interfaces with different mechanical mismatches (strength and hardening mismatches) has been investigated based on finite element analysis and experimental data validation. The results show that with increasing crack depth (geometric constraint) and mechanical mismatch level (increasing undermatch or overmatch level), the J-R curves and fracture toughness J C of bi-material interfaces decrease. The constraint parameter A d * values of bi-material interface cracks are basically independent of the strength and hardening mismatches. A general correlation equation between fracture toughness J C and constraint parameter A d * has been obtained, which may be applied to prediction of fracture toughness of any specimens or components with different geometric constraints and material properties mismatches (including homogeneous materials). The prediction capability of the correlation equation has been validated by experimental fracture toughness data of cracks with different strength and hardening mismatches in dissimilar metal welded joints.
