In this study, the critical damage value of normalized Cockcroft-Latham is determined using ductile fracture criterion to define fracture energy True stress-strain value and materials' properties were obtained by the tensile tests of zirconium alloy 702 and finite-element analysis. It was observed that the maximum value of fractured specimen occurred in the central area of the cross-section, where the highest critical damage value equals 0.649. This paper explored the rarely researched data of zirconium alloys through the inverse analysis method of the FEA. The results were proposed to evaluate the forgeability, and the present study could be used as a basis of designing and developing zirconium alloy.
