An Exploratory Study of Damage Accumulation Methods for Propagating Fatigue Cracks.

Abstract

This report presents three methods that predict damage/accumulation and crack initiation lives for notched laboratory specimens that were subjected to stepwise increasing load. Constant load amplitude and monotonic tensile tests provide the necessary baseline data for establishing the relationship between cyclic loads applied and the damage accumulation process.
