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.
