Effect of Elastic Constants on Stress In A Composite Under Plane Deformation

Abstract

When a composite body consisting of two isotropic and elastic phases is subjected to prescribed surface tractions, generally the stress field depends on three parameters involving the elastic con stants. If the composite is in a state of plane deformation, and there are no net forces on internal boundaries, however, the stress depends on only two combinations of elastic constants. Convenient constants for the composite material are proposed.
