Finite Element Analysis of Functionally Graded Piezoelectric Beams
In this paper, the static bending, free vibration, and dynamic response of functionally graded piezoelectric beams have been carried out by finite element methodunder different sets of mechanical, thermal, and electrical loadings. The beam with functionally graded piezoelectric material (FGPM) is assumed to be graded across the thickness with a simple power law distributio...
متن کاملSimulation of a Microgripper with Electrothermal Actuator Using COMSOL Software Based on the Finite Element Method
Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...

متن کاملModeling Rate-dependent Hysteresis in Piezoelectric Actuator
Hysteresis of a piezoelectric actuator is ratedependent. Most hysteresis models are based on elementary rate-independent operators and are not suitable for modeling actuator behavior across a wide frequency band. This work proposes a rate-dependent modified PrandtlIshlinskii (PI) operator to account for the hysteresis of a piezoelectric actuator at varying frequency. We have shown experimentall...
متن کاملTheoretical Formulations for Finite Element Models of Functionally Graded Beams with Piezoelectric Layers
In this paper an overview of functionally graded materials and constitutive relations of electro elasticity for three-dimensional deformable solids is presented, and governing equations of the Bernoulli–Euler and Timoshenko beam theories which account for through-thickness power-law variation of a two-constituent material and piezoelectric layers are developed using the principle of virtua...
