Tensile stress concentration and compressive failure in cemented granular material

Grain crushing and pore collapse are important micromechanical processes responsible for hydrostatic and shear‐enhanced compactions in porous rocks. These processes initiate from extensile microcracks which emanate from grain contacts. Microstructural observations indicate that such extensile cracking is inhibited in the vicinity of cemented grain contacts. The finite element technique was used to simulate the tensile stress concentration and...
