Evaluation of Crack Growth in Advanced P/M Alloys.

Abstract

This program evaluates the crack growth characteristics of the advanced P/M alloy AF2-1DA. An interpolative model, developed in an earlier program, is used to describe crack growth properties at various conditions. Results are presented, including applicability of linear elastic mechanics (LEFM) and the effects of frequency, stress ratio, and temperature on crack propagation rates. (Author)
