Article English OPEN
Lin, Qibin; Cao, Ping; Wang, Peixin;

In order to build the post-peak strain softening model of rock, the evolution laws of rock parameters m,s were obtained by using the evolutionary mode of piecewise linear function regarding the maximum principle stress. Based on the nonlinear Hoek–Brown criterion, the a... View more
