Title

Development of a Reversible Bending Fatigue Test Bed to Evaluate Bulk Properties Using Sub-size Specimens

Abstract

A non-standard fully reversible bending fatigue test bed of fixed displacement amplitude type was designed. A sub-size sample similar in design to the standard ASTM B593 sample was used to evaluate the high cycle bend fatigue behavior of 7075-T6 sheet specimens. Fatigue life was determined at four stress levels of 300, 240, 220, and 190 MPa at a stress ratio of −1.
