Crack in functionally graded piezoelectric strip bonded to functionally graded strip under electromechanical loading

The problem of a crack in a functionally graded piezoelectric(FGPM)strip bonded to the functionally graded strip is investigated in this paper.It is assumed that the elastic stiffness,piezoelectric constant and dielectric permittivity of the FGPM vary continuously along the thickness of the strip.The crack is assumed to be either electrically impermeable or permeable.Integral transforms and dislocation density functions are employed to reduce...
