... because in the linear elastic fracture mechanics (LEFM) and the cohesive crack model (CCM), the crack is assumed to be a line (of zero width at crack front), while a line cut along the direction of a uniform uniaxial stress field produces no stress change. The transverse normal stress σ zz has also...
