Abstract: The yield criterion of rock is significant for the identification of the whole failure process and the stability analysis of rock engineering. Studies of yield criteria from energy aspects are critical but rare. This paper ...

Abstract: The natural structure of columnar jointed rock mass (CJRM) is complex because it was formed during the cooling process of volcanic rock. In CJRM, both the structures of columns and columnar joints are oriented, and the ...

Abstract: It is of crucial importance to develop an efficient numerical method to investigate the mechanism of grout diffusion and migration in fractured rock masses. However, most existing models only concentrate on the grout flow ...

Abstract: Shale formations as major unconventional energy resources are crucial in satisfying the global energy needs of the future. Via nanoindentation method and upscale method, the macromechanical parameters of shale, such as ...
