Micromechanics determination of effective material coefficients of cement-based piezoelectric ceramic composites

Abstract

Determination of effective composite properties for a real distribution of piezoelectric particles in cement matrix is considered using a representative volume element. The scaled boundary finite element method is proposed to analyse cement-based piezoelectric ceramic composites. Quadtree hierarchical meshing structure is utilized to provide a mesh that captures the material variation in the representative volume element effectively based on the colour of the piezoelectric composite’s image. Analyses with carefully selected boundary conditions are performed to obtain the effective material properties of various samples.
