Abstract A new criterion for predicting metal failure effects under cyclic loading conditions is derived from an innovative elastoplasticity model established most recently. As compared with usual approaches, novel results this are presented in four respects: (i) both low and high cycle fatigue can be simultaneously simulated a unified direct manner; (ii) cumbersome trial‐and‐error procedures i...

Determining the caving height in block method requires considering a suitable criterion discussed this study. The comparison between different criteria and choosing appropriate for use rock mass cavability study is main idea of study, which has not been investigated previous studies. In paper, through FEM (Finite Element Method) software, area undercutting stages was calculated using displaceme...
