Introduction Piezoelectric materials are widely used in engineering because of their specific excellent properties.
But delamination damage will emerge in piezoelectric materials during the manufacturing processes, for instance, shocks in assembling procedures, and it will has effects on dynamic characteristics of structures.
The material properties are given as follows The geometrical parameters of the delaminated piezoelectric shell are.
