An impermeable interfacial crack problem in two dissimilar magnetoelectroelastic half planes has been solved in a compact form by Stroh formulism. The expression for energy release rate has been derived. By using the expression, the overall average properties of the composite have been established in relation to the interface crack density. Results indicate that the presence of interface cracks, as a whole, would deteriorate the coupling effects in the magnetoelectroelastic composites.

Key Words: Impermeable • interface crack • effective properties • magnetoelectroelastic.
