Abstract

This study was initiated to examine the dispersion of longitudinal and transverse waves in metal matrix composites, in order to obtain the dynamic elastic modulus and to evaluate various models for predicting the composite’s macroscopic elastic constants from the properties of its constituents. The materials chosen for this investigation was alumina continuous fibers on the one hand and alumina short fibers on the other hand embedded in an aluminum alloy matrix. In more, some indications have been obtained for the residual stresses in the matrix, the acoustoelastic effect in the composite, the fatigue life of a specimen subjected to sinusoïdal tension-tension metal fatigue at the temperature of 120 °C.
