Uterine contractions during pregnancy are currently poorly understood – experts disagree on the mechanisms by which contractions propagate through the organ and the structural layout of the uterine muscle fibers. We have developed a multi-scale model of the uterus, at the cellular, ... Read More

Thermo-Mechanical Analysis of Composite Material Exposed to Fire

A. Davidy[1]
[1]IMI, Ramat Hasharon, Israel

This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of ... Read More

Modeling and Design of Material Inkjet Printer Ultraviolet LED Curing Cartridges Using COMSOL Multiphysics® for Printed Electronics Applications

M. Guvench[1], R. Wiswell[1]
[1]University of Southern Maine, Gorham, ME, USA

COMSOL Multiphysics® coupled with Solidworks® is employed to design, simulate and fabricate cartridges for a materials printer to accomplish in-situ curing of UV curable ink patterns as they are printed on flexible media for printed electronic circuit manufacturing. The cartridges ... Read More

Heat Generation from Dielectric Loss, Internal Heat Generation and Vibration in COMSOL4.2 Multiphysics

T. R. Jeba, B. Vins, and V. Ramamoorthy
HCL Technologies

This paper presents a FEA approach to estimate temperature rise and thermal stress experienced in PZT/Solid structure due to internal heat generation and dynamic excitation. The power dissipative density consumed by structural damping of the mass structure, internal heat generation due ... Read More

The Friction Coefficient of Fractal Aggregates in the Continuum and the Transition Regimes

Aerosol and colloid aggregates are complex fractal-like structures composed of primary spheres. The drag force exerted on a fractal-like object is usually determined by solving numerically the Stokes equation. In this study we calculate it by relating it to a molecule-aggregate collision ...

Numerical Simulation of Magnetic Drug Targeting with Flow – Structural Interaction in an Arterial Branching Region of Interest

A. Morega, A. Dobre, and M. Morega
University Politehnica of Bucharest, Bucharest, Romania

We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image ... Read More

Gallium nitride (GaN) and its related nitride alloys with special physical properties are in technical areas of high interest. The growing of gallium nitride boules on non-native sapphire or silicon carbide requires complicated mechanisms of defect reduction in the lattice structure. ... Read More

Multiphysics Analysis of a Thermo-Acoustic MHD Inductive Generator

R. Forcinetti [1], S. Carcangiu [1], A. Montisci [1],
[1] DIEE, University of Cagliari, Cagliari, Italy

Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... Read More
