Journal Article 2016 09 24 In this study using ductile fracture criterion defined fracture energy, determining the critical damage value of normalized Cockcroft –Latham. True stress-strain value and materials properties were obtained from the tensile tests of zirconium alloy 702 and finite element analysis. It was observed that specimen fracture the maximum value occurred in the central area of the cross section, the highest critical damage value equal to 0.649. In this paper, through the inverse analysis method of the FEA to explore on rarely research data zirconium alloys. The results proposed to evaluate the forgeability, expect the present study could be used as a basis of designing and developing zirconium alloy. https://scientiairanica.sharif.edu/article_20174_2e88d7e4cf5e19975ae185cea263299f.pdf
