This article is about the one of the main questions of ensuring the fatigue strength of steel elements. Questions of this kind are extremely important and usually considered at the designing calculations stage. Modified δ - damage assessment model is based on energy criteria using experimental data on laboratory samples with different types of concentrators. Results are based on the maximum stress gradients values in the concentrator areas.
