Numerical simulation and experimental verification studies on a unified strength theory-based elastoplastic damage constitutive model of shale
The purpose of this study is to establish an elastic–plastic damage constitutive model of shale and simulate the elastic–plastic damage characteristics of shale under stress. Based on the unified strength theory and the mechanics of shale rock samples characterized in laboratory tests, a new elastic...
