Improvement of Structural Elements Durability by Deep Plastic Deformation

The paper considers the influence of the preliminary plastic deformation on the durability based on the results of numerical studies of the preliminary plastic deformation in the vicinity of a hole in a thin sample by compression with a flat punch, followed by complete unloading and cyclic tension of the specimen. A comparison of the samples durability after the preliminary plastic deformation with the previously undeformed sample is given.
