A coupled micro–macromechanical analysis of hygrothermoelastic composites

A micro±macromechanical procedure is developed to establish the response of multiphase composites whose constituents behave, in general, as hygrothermoelastic materials. The response of the single phase is governed by the fully coupled theory of heat, moisture and deformation, and the micromechanical theory provides the hygrothermoelastic behavior of the composite. Results are presented to illustrate the e€ects of coupling between temperature, moisture and stress, and the interaction between the phases on the overall temporal and spatial response of a composite slab.
