As an important part of the smart/intelligent structures, the composite plate with piezoelectric-ceramics (PZT) patches embedded has numerous values in many engineering applications, such as: aerospace, automotive, civil and mechanical engineering. A composite thin plate excited by PZT actuators is considered in this work. To describe the dynamic response of the quadrate plate clamped at its ...

As biologists uncover the structural and functional complexity of living organisms, it is increasingly clear that mathematical models are needed to synthesize experimental data and predict biological responses to external stimuli. Bioengineers are well-suited to develop such models and to add mechanics, fluid flow and other physical cues to the understanding of biological structure and ...

At Rensselaer Polytechnic Institute we have altered our undergraduate and graduate curricula so that we now teach transport phenomena (heat, mass, momentum, charge) in a holistic manner rather than as discrete courses. The traditional pencil-papercalculator toolset was found lacking and so we turned to FEMLAB® as a teaching tool to help enhance student understanding. In this paper, I will ...

We are investigating the feasibility of using FEMLAB as an integral part of the educational experience of chemical engineering students at Worcester Polytechnic Institute. Our current practices and immediate plans for using FEMLAB in teaching include homework and projects in a graduate course, simulations of unit operations laboratory experiments for use as pre-lab preparations for actual lab ...

A diode radiation detector is often used for in-vivo patient dosimetry to verify overall patient treatment quality with respect to calculation, setup, and delivery for radiation therapy. The non-linear differential equation for the transient response of radiation current was solved numerically using FEMLAB to determine the diode sensitivity as a function of instantaneous dose rate. The numerical ...
Flow Diversion around Elliptical Inhomogeneities Modeled with FEMLAB and the Analytic Element Method

Sudden transitions in hydraulic properties in natural porous media systems associated with deposited inhomogeneities can lead to large diversions flow around or convergence of flow toward the inhomogeneity. Modeling of these features within large unsaturated zones containing such inhomogeneities is challenging because of the need for refined discretization near the boundary of the ...
Finite element modeling of the field enhancement phenomenon in nanoscale field emitters and field ionizers
Ramin Banan Sadeghian and Mojtaba Kahrizi,
Interest in nanoscale field emission and field ionization devices has been renewed in recent years. Several new materials and novel device concepts have been introduced with promising field emission (FE) and field ionization (FI) behavior. Among them vertical ZnO nanowires (ZnONW) exhibit unique FE properties at relatively low applied electric fields. Using FEMLAB, we employed finite element ...

This paper deals with the study of the effects of tissue parameters, such as electrical conductivity and permittivity on the electric field distribution of a rat mesenteric vasculature model under electroporation conditions. Electroporation is a nonviral, physical technique that involves transient dielectric breakdown of the cell’s plasma membrane when high intensity and short duration ...
