Investigation of Cumulative Fatigue Damage for Selected Materials

Abstract

A direct Tension-compression fatigue testing machine Model DS-600 HLM is procured, installed, and calibrated for the generation of data to study the cumulative fatigue damage in selected materials. An apparatus and step-by-step procedure are developed to electropolish the fatigue specimen. Experimental data are generated using 2011-T3 aluminum alloy specimens under completely reversed condition for Low-High and Low-High-Mixed stress cycles. Analysis of the data has indicated that the predicted cumulative fatigue damage and fatigue life are in complete agreement with the experimental values.
