The paper presents an investigation of effective properties of piezocomposites of piezoceramic/polycrystallites type by using the effective moduli method, the computer modeling of representative volumes with random structure of granular heterogeneity and the finite element method to solve the homogenization problems. The effective moduli, obtained from the problems with different boundary conditions on the edges of representative volumes, are analyzed.
