Having completed the general formulation for temperature, heat flow, d
isplacement, electric potential and displacements and mechanical stres
ses of a piezoelectric material as presented in part I of this work, p
art II is concerned with a generalized self-consistent approximate met
hod for determining the thermoelectroelastic properties of piezoelectr
ic materials weakened by microcracks. A representative area element is
adopted; it contains a microcrack surrounded by an elliptic matrix in
a solid with effective properties, Numerical results are given for a
piezoelectric BatiO(3) ceramic. The effective conductivity and effecti
ve modulus are found to decrease with increasing crack density.
