With the aid of the ANSYS® FEM-packet, solution is offered with regard to the fracture mechanics for cylindrical panels with blind surface cracks of semi-elliptical shape. Obtained was distribution of the J-integral lengthwise the defect front, the values of which are calculated via the integration technique by area. Application of the cellular mesh with major number finite elements lengthwise the front line enables detection of the boundary effect near the crack front penetration to the surface. Offered are universal equations for estimating values of the stress intensify factor in the front characteristic points.
