Abstract: This work shows the comparison of stress field distribution in front of the crack front from both vertex singularity and out-of-plane constraint description. The three-dimensional numerical simulations of the middle crack tension specimen are performed. Relevant fracture mechanics parameters are estimated using finite element simulations and used for semi-analytical stress field descriptions mentioned. Good agreement between out-of-plane constraint methodology and vertex singularity methodology was found.
