Simulation of inverse Piezoelectric effect in the Abaqus

Project Overview

In this Abaqus project, the inverse piezoelectric effect is simulated and investigated.

Two piezoelectric strips are attached to the top and bottom surfaces of a composite beam. The piezoelectric material used in this model is PZT-5H.

PZT-5H Piezoelectric Material

The piezoelectric strips are made of PZT-5H, a piezoelectric material that can convert electrical energy into mechanical deformation when an electric potential difference is applied.

In this simulation, the electrical response of the PZT-5H material is coupled with its mechanical behavior to investigate the deformation generated by the applied voltage.

Application of Electric Potential

An electric potential difference of 1000 V is applied to the piezoelectric strips. The applied voltage generates an electric field inside the piezoelectric material.

Inverse Piezoelectric Effect

When an electric potential difference is applied to a piezoelectric material, an electric field is generated inside the material. As a result, the piezoelectric material undergoes mechanical deformation.

This phenomenon is known as the inverse piezoelectric effect, in which electrical energy is converted into mechanical energy.

Electric Field and Deformation

The applied voltage creates an electric field within the piezoelectric strips. This electric field causes the strips to deform, which in turn affects the overall deformation of the composite beam.

Vertical Displacement

The deformation of the composite beam is evaluated after applying the electrical potential. The maximum vertical displacement obtained from the simulation is approximately 10.69 mm.
