Abstract
A unified set of composite micromechanics equations is summarized and described. This unified set is for predicting the ply microstresses when the ply stresses are known. The set consists of equations of simple form for predicting three-dimensional stresses (six each) in the matrix, fiber, and interface. Several numerical examples are included to illus trate use and computational effectiveness of the equations in this unified set. Numberical results from these examples are discussed with respect to their significance on microcrack formation and, therefore, damage initiation in fiber composites.
