WebThe Mohr-Coulomb criterion assumes that failure is controlled by the maximum shear stress and that this failure shear stress depends on the normal stress. This can be represented by plotting Mohr's circle for states of stress at failure in terms of the maximum and minimum principal stresses. WebA ductile fracture model is included based on Hosford-Coulomb fracture initiation model. This model applies to both shell and solid elements. To make this material model more general and flexible, three load curves are used to define the three components of the deformation resistance. WebThe Hosford–Coulomb (HC) model of Mohr and Marcadet is also phenomenological like the MMC model but is notable in that the functional form was determined from an exhaustive numerical study of the localization and failure of voided unit cells by Dunand and Mohr . The MC model provided a reasonable approximation to the numerical failure data ... ffc 2896
