Overall properties of piezoelectric composites with spring-type imperfect interfaces using the mechanics of structure genome

In this study, the mechanics of structure genome has been extended to piezoelasticity problem of composite materials with spring-type imperfect interfaces model. This full field micromechanics approach is applied to predict the effective electro-elastic properties of piezoelectric composite materials containing imperfect contact between the matrix and the reinforcements. Examples of long fibers and spherical particles reinforced piezoelectric composite materials are used to demonstrate the robustness and accuracy of the proposed micromechanics theory. The size-dependency of the overall electro-elastic properties shows the importance of imperfect interfaces in modeling the electro-elastic behavior of composite materials.
