The piezoelectric materials have become indispensable in many technological applications. These materials
have an inverse piezoelectric effect which allows them to control the form and to present any neither noise nor
vibration at any time or position on the structure. In this study we are interested in the bending behavior analysis
and modelling of a ceramic beam under external solicitations using numerical simulations based on the finite
element methods. The modelling permit to simulate the deformations in a piezoelectric ceramic beam subjected to
an electric field and to simple mechanical stress taking into account the electromechanical coupling. It has been
found that the obtained analytical results are in a very good agreement with those obtained by numerical
modeling. As a result, the interest of such modelling analysis allows the design, the conception and the
optimization of mechanical systems based on piezoelectric elements. These materials known as smart or
“intelligent” materials, are often used to measure and/or to control finite deformations or vibrations in mechanical
systems, so that to prevent their plastic deformations or their total failure
