Durability of a Stress Concentrator-Containing Cantilever Beam Under Cyclic Loading in Bending

The procedure and results of studies on the durability of the cantilever beam metal over the stress concentrator area in pulsed cyclic bending are presented. Comparison of experimental and numerical simulation data resulted in establishing the relation between the durability and cyclic inelastic strain amplitude. The effect of strain hardening and plastic strains on durability was elucidated.
