A micromechanics model for composites under fatigue loading

Based upon an average stress formulation of composite materials derived from the Mori-Tanaka method, a fatigue criterion is established. The criterion is at the micromechanics level, and addresses the failure of all the constituents of the composite and represents the interactions between the consti...

Zusammenfassung:	Based upon an average stress formulation of composite materials derived from the Mori-Tanaka method, a fatigue criterion is established. The criterion is at the micromechanics level, and addresses the failure of all the constituents of the composite and represents the interactions between the constituents of the composite by involving the volume fraction, the properties of the constituents and the interfacial bond. Predictions of the S N curves for E-glass/epoxy laminae under off-axis loading are compared with the existing experimental data.
