The cohesive zone model used to simulate tissue cleavage process. (a) A sketch depicting application of cohesive zone elements along the bulk element boundaries, where tensile/compressive (normal) and shear strains result in deformation and rupture of the cohesive elements. (b) Linear traction-separation laws where values for Kn, Ks, Gc, and tc are obtained from experiments and given in Table I.
