Multi-objective Optimization of Microneedle Design for Transdermal Drug Delivery

M. Sarmadi [1], K. McHugh [1], R. Langer [1], A. Jaklenec [1],
[1] David H. Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology, Cambridge, MA, USA

Microneedles have been recognized as a potent and novel method of transdermal drug delivery over the last decade. Despite recent advances in nano- and microfabrication techniques, less is known about the structural properties and design optimization of microneedles in a systematic ... Read More

COMSOL® Modeling and Tensile Loading of Aluminum Material Test Samples

J. L. Palladino [1],
[1] Trinity College, Hartford, CT, USA

Material test samples are commonly subjected to tensile testing, with an extensometer used to measure changes in length of the material to determine strain. Lacking an extensometer, strain gages were used to measure longitudinal and transverse strain, with the location and magnitudes of ... Read More

Simulation of Adsorption Mechanisms of Methane and Carbon Dioxide in Shale Matrix

J. G. Moreira [1], A. L. Manriquez [1],
[1] Texas A&M University - Kingsville, Kingsville, TX, USA

The aim of this research is to contribute with the development of Carbon Capture and Storage techniques by studying carbon dioxide (CO2) adsorption mechanisms in shale reservoirs. Gas desorption is considered a major gas production mechanism and has a relevant role in shale gas ... Read More

The Numerical Challenges in Multiphysical Modeling of Laser Welding with ALE

I. Tomashchuk [1], I. Bendaoud [2], J.-M. Jouvard [1], P. Sallamand [1],
[1] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université de Bourgogne-Franche-Comté, Le Creusot, France
[2] Laboratoire de Mécanique et Génie Civil, Université de Montpellier, France

The interaction of high power laser beam with metallic materials produces a number of interconnected phenomena that represent a serious challenge for numerical modeling, especially for creation of auto-consistent models. Additional difficulty consists in lack of data on materials ... Read More

Comprehensive Numerical Modeling of Filamentary RRAM Device

D. Niraula [1], V. Karpov [1],
[1] University of Toledo, Toledo, OH, USA

Resistive random-access memory (RRAM) is a non-volatile memory that operates via resistive switching between the insulating (OFF) and conducting (ON) states, representing the logical ‘0’ and ‘1’ binary states, in response to external bias. Attributes such as high memory density, fast ... Read More

Finite Element Prediction of Laser-Material Interaction Using COMSOL Multiphysics®

E.C. Chevallier [1], V. Bruyère [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Surface engineering is a key technology used in a wide range of sectors in industry. Among other techniques, it involves adding functionality to a surface. This can be performed by creating a specific topography to a surface using laser texturing. The objective of the work presented in ... Read More

Keynote Talk: Audio Product Development at Samsung Audio Lab Better and Faster With Simulations

Andri Bezzola
Samsung Research America, USA

An audio loudspeaker is inherently a multiphysics apparatus: It converts an electrical signal to acoustic waves by moving a structural membrane via an electromechanical voice coil. As the signal travels from the record medium to the human ear, coupled linear as well as nonlinear ... Read More

Simulation of CVD Process in a Reactor

A. Kulkarni [1], F. Mumme [1], V. Frettlöh [1],
[1] Gemeinnützige KIMW Forschungs-GmbH, Lüdenscheid, NRW, Germany

Metal-organic chemical vapour deposition (MOCVD) is a well-known process to produce high quality thin films that can protect, ennoble and functionalize metallic tools. To realize a high performance coating on a complex 3D mold surface, knowledge about the material formation from a ... Read More

Automated Meshing of Evolving Microstructures from High-Throughput Grain Growth Simulations

M. Golt [1], E. Hernandez-Rivera [1],
[1] U.S. Army Research Laboratory, Aberdeen Proving Ground, MD, USA

Microstructure evolution simulations using the kinetic Monte Carlo algorithm and the phase field method are routinely used to model and simulate sintering and densification of ceramic and metallic materials. Understanding evolution of microstructural features is important as these are ... Read More

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... Read More
