Abstract
- An analysis model of the dynamic properties of 2–2 multi-layered cement-based piezoelectric composite under impact load and its definite problems are investigated based on the theory of piezo-elasticity in this paper. The theoretical solutions are obtained according to the Duhamel integral and variable separation method. After analyzing the physical meaning and the convergence of the theoretical solutions, the numerical simulations of the composite are presented by utilizing the various loads including the transient step, the transient haversine wave and the transient isosceles triangle loads. The theoretical solutions are compared with the numerical simulations, as well as reported results. Excellent agreements among these results are found. In addition, the influences of the number of layers of the composite and the piezoelectric parameters on the response of dynamic properties are discussed. The work could benefit the design and preparation of the 2–2 multi-layered cement-based piezoelectric composite in engineering practice. [ABSTRACT FROM AUTHOR]
