Abstract

In this paper, the static problem of several cracks in a functionally graded piezoelectric– piezomagnetic (FGPP) rectangular plane subjected to concentrated anti-plane mechanical and in-plane electric and magnetic fields is described. The material properties are assumed to vary continuously according to exponential functions along the transverse of the FGPP rectangular plane. The dislocation method and integral transforms technique are applied to obtain a set of Cauchy singular integral equations. The field intensity factors for cracks, are obtained by using the corresponding solution to these equations. The numerical examples of mode-III problem are presented to illustrate the interesting mechanical and electromagnetic coupling phenomena induced by multi-crack interactions. Finally, the effects of material non-homogeneity constant, the cracks length and the cracks configuration upon the field intensity factors are investigated. The obtained conclusions seem useful for design of the magneto-electro-elastic structures and devices of high performance.
