AbstractUsing the integral transform and the Cauchy singular integral equation methods, the problem of interface cracks between dissimilar magneto-electro-elastic strips under out-of-plane mechanical and in-plane magneto-electrical impacts is investigated. The magneto-electric permeable boundary condition on the crack surfaces is adopted. The number of the interface cracks is arbitrary. The field intensity factors and energy release rates are derived and discussed. The effects of the crack configuration and the main constitutive parameters of the magneto-electro-elastic materials on the dynamic response are examined. Results show that the dynamic energy release rates (DERRs) as the crack extension force are quite equivalent to the dynamic stress intensity factors (DSIFs) for magneto-electric permeable interface cracks. The DERRs may be retarded or accelerated by specifying different combinations of material parameters. In addition, the parameters of the crack configuration, including the ratio of the strip width to the crack length, the ratio of the widths for different strips, and the distances between two cracks, exert a considerable influence on the DERRs. The results seem useful for design of the magneto-electro-elastic composite structures and devices of high performance. © 2005 Elsevier Ltd. All rights reserved.
