Fatigue Behavior of Unidirectional Fp-Al Composites with Circular Holes.

Abstract

This investigation examines the response of the FP-AL system under both tensile and compressive cyclic loads, and also in the presence of circular holes. A related analysis of elastic-plastic deformation of the specimens under cyclic loading has been performed and used in interpretation of the experimental data. Of particular interest here was an examination of the relationship between shakedown and onset of fatigue damage in the aluminum matrix. Magnitudes of fiber stress in the vicinity of the circular holes under cyclic loading were evaluated as well. The fatigue damage modes, under various loading conditions were also examined. This report describes the experimental program, its results, the plasticity analysis of test specimens, and interpretation of the experimental data. Keywords are Metal matrix composites, Fiber reinforced composites, Aluminum, Fatigue, Composite materials, Stress concentration, Aluminum oxide fibers.
