Abstract: The problem of optimizing the bearing capacity of a stringer panel with a hole and a straight crack propagating from its contour is considered. The goal is to determine a hole contour at which the stress intensity factor in the vicinity of the crack tip is equal to zero (i.e., the crack is immobile) and at which the maximum circumferential stress is the smallest. A minimization problem is solved using the method of successive approximations, the minimax criterion, and the simplex algorithm.
Keywords: stringer panel, stress state minimization, straight crack, optimal hole shape, minimax criterion.
