Assessment of Durability of Steels and Alloys under Dynamic Loading

The article presents mathematical models developed for the purposes of assessing inelastic deformation of steels and alloys under stress loading at the fatigue limit level, critical dislocation density, fracture toughness, and number of cycles to failure. The obtained dependences can be used to develop optimal designs of products and technologies for further manufacture and thus increase durability of the relevant parts and materials.
