Abstract


Cutting edge composite materials now play an essential role in micro/nano-structural systems. Micro/ Nano particles and/or structural systems are embedded into a material matrix in order to enhance material properties, and make them a "smart material". A widely used type of smart material is piezoelectric materials, which have the property of piezoelectricity - an electromechanical effect that occurs in some micronano-structural materials. A further electromechanical effect called the flexoeletric effect is also induced due to the fact that strain gradient on the micro/nano scale provides an electrical polarization. In this work, the Finite Element Method (FEM) formulation for beam theories was used to investigate materials including both piezoelectric and flexoelectric effects. The variational form of 2D piezoelectric nanobeams with flexoelectric effect are also presented and be solved by FEM. The results from beam theories and 2D planar beam will be compared with analytical solutions and other numerical techniques.
