  • A new approach is presented herein to predict the failure of metallic materials. A failure criterion that caters for the effects of stress triaxiality and Lode parameter is proposed and it is applicable not only to metals with ēf > ef but also to metals with ēfef , here ēf and ef are the two parameters defined as the true strains at stress triaxiality of η = 1/3 for Lode parameters of ξ = 1 (axisymmetric stress state) and ξ = 0 (plane strain state) respectively. Furthermore, only two laboratory tests such as smooth bar tension test and pure shear test are needed to calibrate the failure criterion. The present failure criterion is proved in good agreement with the test data for various metals under different loading conditions.
