Sensing Analysis of Piezoelectric Composite Beam

The objective of this paper is to analyze the smart composite beam integrated with a piezoelectric layer to use in sensing simulation. The beam consists of an 8-layered [0/45/-45/90]S bottom CFRP composite layer and an upper PZT layer as a piezoelectric sensor. Linear 3D piezo-elasticity theory for static analysis has been utilized. A prescribed downward displacement is applied at the free end of the cantilever beam to obtain the voltage and electric field results of the outer surface of the piezoelectric layer. The analysis of the piezoelectric composite beam is performed by ADINA FEM analysis.
