Abstract

The aim of this work is to demonstrate a fully explicit analytical micromechanical self-consistent approach dedicated to mechanical states prediction in both the fiber and the matrix of composite structures submitted to a transient hygroelastic load. The analytical forms obtained are applied to the case of carbon-epoxy composites. Rigorous continuum mechanics formalisms are used for the determination of the required time and space-dependent macroscopic stresses. The reliability of the new approach is checked through a comparison between the local stress states calculated in both the resin and the fiber according to the new closed-form solutions and the equivalent numerical model.
