An engineering method for assessing fatigue life, taking into account the accumulation of damage and allows determining the trajectory of the fatigue crack. The calculation is performed by successive approximations based on the ANSYS Mechanical APDL software package in both linear and nonlinear installations. Stages of calculation of fatigue, cracking and fatigue failure of the structure alternate.
