摘要: The initiation and propagation of microfractures their contribution to material failure in compression are examined. early part the fracture process, lateral axial yield points stress-strain curves, identified with onset microfracture, respectively at tensile compressive stress concentrations elastic flaw boundary. Later stages, including inclined shear fractures, mobilization total resistance reduction strength residual level, discussed terms a modified Coulomb model.
