Cyclic Inelastic Deformation and Fatigue Life Behaviour of Notched Components.
Abstract
Cyclic inelastic deformation response and fatigue notch factor are presented and discussed for two metals of contrasting stress-strain behaviour (an aluminum alloy 2024-T351 and a mild steel SAE 1015). Thin circular or elliptical notched plates fabricated from these metals were subjected to cyclic straining in a servo-controlled testing machine. Results of these tests are discussed in terms of cyclic stress and strain concentration factors and related to notch plate deformation through a parameter derived fron Neuber's rule. The results indicate that the deformation analysis employed, rather than a material 'size effect' is responsible for values of K sub f less that K sub t. (Author)
