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 کاملUsing Finite Element Analysis and Experimental Analysis on Vibration of a Piezoelectric Micro Pump
Due to the rise of biological and MEMS technology in recent years, some micro flow system components have drawn attention and been developed by many investigators. The importance of micro-pumps manufactured is higher than the other part of micro flow system since it is the power source of the entire micro-flow system and responsible for driving working fluid in the microfluidic system. In actua...
متن کاملMultiscale behavior of crack initiation and growth in piezoelectric ceramics
The multiscale nature of cracking in ferroelectric ceramics is explored in relation to the crack growth enhancement and retardation behavior when the direction of applied electric ®eld is reversed with reference to that of poling. An a priori knowledge of the prevailing fracture behavior is invoked for the energy dissipated in exchange of the macroand micro-crack surface. To avoid the formalism...
متن کاملDesign Study of Piezoelectric Micro-machined Mechanically Coupled Cantilever Filters using a Combined Finite Element and Microwave Circuit Analysis
A new mechanical filter structure is presented which comprises two silicon cantilevers mechanically coupled by a silicon linkage with thin film piezoelectric transducers providing electrical input and output signals. The resonance behaviour of such a structure results in a bandpass filter response, having a band-width determined by the frequency separation between the closely spaced in-phase an...
متن کاملFinite element analysis in functional morphology.
This article reviews the fundamental principles of the finite element method and the three basic steps (model creation, solution, and validation and interpretation) involved in using it to examine structural mechanics. Validation is a critical step in the analysis, without which researchers cannot evaluate the extent to which the model represents or is relevant to the real biological condition....
