Stress fields in composites with coated inclusions

A micromechanics model is presented for the prediction of stress fields in coated fiber composites. The method is based on the "average stress in the matrix" concept of Mori and Tanaka and is formulated for the case of thermoelastic loading. A general description of the model is first given for three-phase materials and then specialized to the case of coated fiber composites. Results are presented for typical coated fiber composite systems under a variety of mechanical loading situations and uniform temperature change.
