The Crack Tip Opening Displacement and Integral Under Strain Control and Fully Plastic Conditions Estimated by the Engineering Treatment Model for Plane Stress Tension

Source

The Engineering Treatment Model (ETM) relates the crack tip opening displacement (CTOD) and the J integral with the applied load or applied strain using a geometry independent, master-curve-type, equation. In the present paper, CTOD and J were examined as a function of the applied strain by means of comparing ETM predictions with earlier experimental and numerical results. A comparison was also made with a theoretical solution by Shih and Hutchinson. It was concluded that the ETM provides useful engineering approximations.
