In this study, the time-dependent damage process of granite is investigated utilizing two numerical simulation schemes based on continuous method and discontinuous method. Numerical creep tests are carried out with both simulation schemes and mechanical responses and fracture patterns of rock specimens are analyzed. The calibrated numerical models can successfully reflect the typical creep stages...
Time-dependent crack growth in brittle rock has been studied utilizing the proposed numerical models. The modeling schemes are developed based on the theory of subcritical crack growth, linear elastic fracture mechanics and Charles equation. The lifetime prediction schemes were introduced. Simulation results of different numerical models were compared. Preliminary studies were also performed to simulate...
