Prediction of Elastic Constants of Multi-Phase Materials

Abstract

The energy theorems of elasticity theory are used to find upper and lower bounds on the elastic moduli in tension and shear for two-phasematerials. A "strength of materials" type of approximate solution is also given. Comiparison with experimental data for a particular alloy systemshows good correlation for the approximate solution, with the scatter band bounced by the predicted limits. It is shown that the method may also be used for more general multi-phase systems, and to predict temperature dependence of the elastic constants of the composite material.
