摘要: Abstract In this work, the finite element method (FEM) is used to characterize effective thermo-electro-mechanical material properties of cement-based porous piezoelectric ceramic composites in structural health monitoring (SHM) systems. The micromechanics representative volume (RVE) approach with a realistic distribution particles cement matrix. effects particle fraction and pore on composite are determined using sets different boundary conditions. Results show very good agreement published experimental computational results.
