A micromechanics model for estimating the effective thermoelastic properties of layered media
Source abstract
Abstract
A micromechanics model is presented for estimating the effective thermoelastic properties of layered media. The continuity condition across a perfectly bonded interface between two dissimilar materials is introduced by decomposing the stress and strain tensors into two orthogonal complementary parts, an interior part and an exterior part that are tangential and normal to the interface, respectively. This model follows from the fact that the exterior part of the stress tensor and the interior part of the strain tensor are each continuous across the perfect interface. Thereby, the interaction between different phases of composites is accounted for. The exact expressions for the effective thermoelastic properties of layered media are derived, and the connections between the present scheme and some conventional micromechanics models are examined.
