Interactive Effects of High- and Low-Frequency Loading on Fatigue.

Abstract

This report describes the results of a program to measure and model the controlling mechanisms of fatigue and creep-crack growth behavior of a typical aircraft engine disk material under high frequency/low frequency loading cycles. The goal of the program is to provide a basis for damage-tolerant design of aircraft engine components under combined high and low frequency loading. Keywords: charts; tables(data); crack propagation; life expectancy (Service Life). (Author)
