T-Stress in Elastic-plastic Crack-tip Fields
by Tian, Changlu; Cui, Weicheng
A ligament field ahead of a crack tip for Model-I plane strain problem in a power-law hardening material is developed. Based on this solution, a formula for the critical value of J-integral in terms of T-stress for an elastic-plastic material is derived. T-stress effects on fracture toughness are discussed.
