Static Study of Piezoelectric Bimorph Beams with Delamination Zone
The FOSDT (the First Order Shear Deformation Theory) is taking into consideration to study the static behavior of a bimorph beam, with a delamination zone between the upper and the lower layer. The effect of limit conditions and lengths of the delamination zone are presented in this paper, with a PVDF piezoelectric material application. A FEM “Finite Element Method” is used to discretize the be...
متن کاملElectromechanical Coupling Correction for Piezoelectric Layered Beams
This paper deals with the bending of layered piezoelectric beams (multimorphs) subjected to arbitrary electrical and mechanical loading. Weinberg [1] obtaind a closed-form solution to this problem using Euler–Bernoulli beam theory and integrated equilibrium equations. In his analysis, Weinberg assumes that the electric field is constant through the thickness of the piezoelectric layers. This ap...
متن کاملEvaluation of Analytical and Finite Element Modeling on Piezoelectric Cantilever Bimorph Energy Harvester
Harvesting the electrical energy from their working environment has become a feasible choice of realizing self-powered systems or providing supplementary power sources to the battery. In this paper, a pre-loaded piezoelectric cantilever bimorph (PCB) energy harvester is adopted as the research object, for which a single degree-of-freedom analytical model and finite element modeling have been ca...
متن کاملConnected Vibrating Piezoelectric Bimorph Beams as a Wide-band Piezoelectric Power Harvester
We analyze coupled flexural vibration of two elastically and electrically connected piezoelectric beams near resonance for converting mechanical vibration energy to electrical energy. Each beam is a so-called piezoelectric bimorph with two layers of piezoelectrics. The 1D equations for bending of piezoelectric beams are used for a theoretical analysis. An exact analytical solution to the beam e...
متن کاملTransverse and longitudinal dynamic modeling of bimorph piezoelectric actuators with investigating the effect of vibrational modes
Bimorph piezoelectric cantilevered (BPC) actuators have recently received a great deal of attention in a variety of micro-electromechanical systems (MEMS) applications. Dynamic modeling of such actuators needs to be improved in order to enhance the control performance. Previous works have usually taken transv...
