AN INVESTIGATION OF THE FATIGUE OF ALUMINUM ALLOY DUE TO RANDOM LOADING

Abstract

A study of the aluminum alloy 2024-T4 under random and constant amplitude axial fatigue loading was undertaken using 1500 unnotched extruded bar specimens. In the constant amplitude test series, it was discovered that the stress amplitude endurance (S-N) relation is well represented by two separate failure distributions such that, as the stress amplitude is lowered, the one distribution recedes while the other distribution be comes predominant. The knee of the S-N curve is then considered as a transition from endurances predominantly of the one distribution to endurances predominantly of the other.
