Abstract
In the paper, the authors experimentally investigated the growth of low-alloy steel surface cracks under constant amplitude loading and under single overloads. Surface semi-elliptical cracks of canonical shape, as well as cracks with a contour of complex geometry were considered. Each overload increased the number of cycles of crack growth retardation, with higher significance in non-canonical surface cracks. The contour of surface cracks also changed in single-overload condition.
