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.

Then, a concrete 'super fuzzy' feature model combined by four cent-characteristics for fabric materials is obtained, and this model is optimized.
Finally, after some programs experiments, concrete effect of fabric materials defects denoted by 'super fuzzy' feature is validated.

Introduction Geopolymers may represent new material types on the border among glass, ceramic materials and materials based on classical inorganic bonds [1].
Materials that use less natural resources, require less energy, and generate less CO2 are referred to as green materials.
