Abstract
An improved micromechanical model has been developed to predict the hydrostatic response of 1-3 piezocomposites. The influence of matrix stiffness, interlayer stiffness, rod aspect ratio, and rod volume fraction on the load transfer and the effective hydrostatic piezoelectric voltage coefficient was investigated. Model predictions treat the ceramic rods as transversely isotropic and relax plane strain assumptions by integrating over the non-uniform strains in the rod and matrix. Results of the current model are compared with predictions from a plane strain model. Optimal interlayer and matrix properties for maximum sensitivity are discussed.
