The numerical calculation is carried out to predict the places of fatigue cracks, determine the fatigue life and the path of crack propagation of castellated beams, specifying the possibility of their use under multi-cycle loads. The method was implemented by using of the developed subroutine in the Ansys Mechanical software package in the parametric programming language APDL (ANSYS Parametric Design Language). The calculation is carried out in the form of successive quasi-static iterations.
