Abstract The combined finite-discrete element method (FDEM) can effectively simulate the continuousdiscontinuous failure process of rocks, and is now widely adopted to investigate the issues related to rock
mechanics and engineering. The conventional FDEM requires pre-defines constitutive models to calculate
the element stress from element deformations [1]. However, the constitutive model used in conventional
FDEM is obtained by empirical fitting of rock mechanics test data, and large amount of rock physical and
mechanical information present in the test data, such as the nonlinear properties of rock presented in the
initial compaction stage, are lost in the… More >
