Using COMSOL to Support a Cost-Effective, Non-Destructive Evaluation Approach for Predicting Bolt Failure in Highway Bridges

A. Elyea, B. Doubek, G. Hubbard, and D. Ozevin
Department of Civil Engineering
University of Illinois at Chicago
Chicago, IL

The development of a quantitative nondestructive evaluation method, as an alternative to visual inspection, for inspecting pre-tensioned bolts in fracture critical bridges is presented. In order to understand the ultrasonic behavior of a wide variety of bolt geometries used in bridges, ... En savoir plus

3-D Design, Electro-Thermal Simulation and Geometrical Optimization of Spiral Platinum Micro-Heaters for Low Power Gas Sensing Applications Using COMSOL 4.1

V. Bansal, D. Kumar, B. Prasad, and A. Gujjar
Electronic Science Department

In this paper a thermal electric finite element method (FEM) analysis was used to investigate the thermal properties of individual electrically driven platinum micro-heaters. The geometric optimization for the micro-heater was performed by simulating a wide range of possible geometries ... En savoir plus

Enhanced Physics-Based Models for State Estimation of Li-Ion Batteries

Daniel Luder¹
¹Berne University of Applied Sciences, Berne, Switzerland

COMSOL Multiphysics® and the Batteries & Fuel Cells Module are used to create a pseudo 2D model of a Li-ion battery. A sensitivity analysis determines the most sensitive model parameters which are identified by microstructure analysis or optimized by nonlinear least-square regression ... En savoir plus

Simulation of Moisture Ingression in Microelectronics Packages to Correlate Test and Field Conditions
