The problem of an anti-plane crack situated in the interface of functionally graded piezoelectric materials (FGPMs) and homogeneous piezoelectric materials (HPMs) is considered under the impermeable assumption of crack surfaces.
However, for the interfacial crack problem of piezoelectric materials, some results have been reported.
Basic equations Fig. 1 shows the configuration of FGPMs bonded to HPMs denoted as materials 1 and 2, respectively.

Obviously, the new design concepts require new materials, and vice versa, new materials often require new, innovative forming processes and new tooling concepts, as well.
These contradictory requirements can be met by using higher strength materials.
From the side of materials science, the application of this design principle can be met by applying materials with high specific strength (UTS/r) and high specific stiffness (E/ r).
