[1]STMicroelectronics, Italy

Plastic packages, coated with Epoxy Molding Compound (EMC) can provide an economic and versatile protection to the integrated circuits (IC) from mechanical damage. A major drawback of molded packages is that they are not hermetic and are prone to absorb moisture from external ... 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

Multiphysics Simulation of the Material State in Single-Screw Extruder

S. Yan [1], H. Zeizinger [1],
[1] Polymertechnology Powertrain, Daimler AG, Stuttgart, Germany

To receive a stable quality in the injection molding process in the view of mechanically and thermally highly stressed components made by reactive resin systems, it is necessary to understand the material state along the processing chain.
