    Abstract

    Local stress-strain analysis is widely used in fatigue life prediction to estimate life to crack initiation at stress concentrators. Smooth specimen cyclic stress-strain curve and Neuber's Rule are used in the analysis for determining local stresses and strains at notches. Cyclic stress-strain curve at a. notch can be different from the smooth specimen cyclic stress-strain curve due to geometry,-stress gradient13; and constraint effects. This work is aimed at determining notch cyclic stress-strain curve for a semi-circular notch on AI-Cu plate material. Details of experimentation are presented in this report.
