A Study of Cutting Temperatures in Turning Glass-Fiber-Reinforced -Plastic (GFRP) Composites with nose radius worn tools

Chang C-S, National Ilan University, TW
Abstract: Nine kinds of chamfered main cutting edge carbide tools were used in turning of glass-fiber-reinforced plastics (GFRP) materials to study the temperature of tip's surface and the cutting forces. Force data from these tests [...]

Combined Device- and System-level Simulation of RF MEMS Switches

Schrag G., Künzig T., Niessner M., Wachutka G., Technical University of Münich, DE
We present two problem-adapted, tailored modeling approaches for RF-MEMS switches which, in principle, are applicable to any capacitive MEMS device. They are based on finite element analysis (FEA) combined with analytical, lumped-element, and reduced-order modeling [...]

Lumped Electro-Thermo-Mechanical Beam Model

Chigullapalli A., Purdue University, US
In this paper we present a lumped electro-thermo-mechanical beam model. Such a model is important for efficiently computing the deflection of an assemblage of mechanical beams that are subject to one or more applied voltages, [...]

Mechanical properties of PECVD Si3N4 thin films with rapid thermal annealing using finite element simulation

Chiang C-Y, Huang Z-K, Chen K.-S., National Cheng Kung University, TW
The entire study includes Si3N4 specimen fabrication, material and mechanical characterization, a new physical model derivation, as well as the corresponding finite element analysis (FEA) and simulations. Nevertheless, the standard method used for nanoindentation were [...]

A Fully Symmetric and Completly Decoupled MEMS-SOI Gyroscope

Sharaf A., Sedky S., Serry M., Elshurafa A., Ashour M., Habib S.E.-D., American University in Cairo, EG
Gyroscopes are sensors that measure rotation rate and are extremely important in many applications such as navigation and vehicle stability control. Despite being manufactured in many technologies in various shapes and sizes, micro-electromechanical (MEMS) gyroscopes [...]

An Online Tool for Simulating Electro-Thermo-Mechanical Flexures Using Distributed and Lumped Analyses

Li F., Clark J.V., Purdue University, US
We present an online software tool that enables both novices and experts to quickly and fairly accurately model and simulate an electro-thermo-mechanical microdevice. We model and simulate a MEMS thermal actuator by coupling finite element [...]

Multiphysics Modeling and Simulation for a MEMS Thermal-Mechanical Switch

Wang W., Popuri R., Onishi S., Bumgarner J., Langebrake L., University of South Florida, US
This paper presents the results of finite element analysis (FEA) modeling and simulation including thermal-electric-structural multiphysics contact phenomenon for a MEMS thermal-mechanical DC switch. The parametric model can be used for design optimizations.The switch consists [...]

FEA Simulation of Thin Film Coils to Power Wireless Neural Interfaces

Kim S., Scholz O., Zoschke K., Harrison R., Solzbacher F., Klein M., Toepper M., Fraunhofer Institute for Biomedical Engineering, DE
To wirelessly transfer energy into active biomedical devices such as neural stimulators or bio-monitors implanted in the body, magnetic coupling of a pair of coils has been commonly used. The growing demand for highly miniaturized [...]

Numerical Modelling of a Microfluidic Ultrasonic Particle Separator

Townsend R.J., Hill M., Harris N.R., White N.M., Beeby S.P., University of Southampton, UK
Particles held in a fluid suspension and within an acoustic standing wave experience an acoustic radiation force. The force causes particles to move to the pressure nodes of the acoustic field creating a concentrate, contributing [...]

Numerical Modeling of a Piezoelectric Micropump

Schlipf R., Haghighi K., Lange R., Purdue University, US
An effective description and an accurate understanding of any pumping mechanism is critical, especially of the micro scale. With the existence of a comprehensive and adaptable model, accurate preproduction predictions of performance are realized. Optimal [...]
