A Mixed Boundary Value Problem That Arises in the Study of Adhesively Bonded Structures

R. Malek-Madani, and J.J. Radice
US Naval Academy, Annapolis, MD, USA

The study of deformation of an adhesively bonded sandwich structure reduces to solving the biharmonic equation for the Airy Stress subject to mixed boundary conditions. Because of the nature of the boundary conditions, this boundary value problem does not yield to the standard elementary ... 詳細を見る

National Institute of Technology Tiruchirapalli, Tamil Nadu, India

A proximity DC current sensor using of a piezo sensed and actuated cantilever beam with a permanent magnet mounted at its free end is designed and simulated in COMSOL Multiphysics. The change in resonant frequency of cantilever is a measure of the current through the wire. The sensor is ... 詳細を見る

MEMS Comb Drive Gap Reduction Beyond Minimum Feature Size: A Computational Study

N. Osonwanne, and J.V. Clark
Purdue University, West Lafayette, IN, USA

In this paper we present a method to reduce the comb drive gap in micro electro mechanical systems (MEMS) beyond the minimum fabrication feature size. The benefit of reducing the gap space between comb drive fingers is to increase its sensitivity to changes in capacitance due to ... 詳細を見る

Modeling of the Bread Baking Process Using Moving Boundary and Arbitrary-Lagrangian-Eulerian (ALE) Approaches
