Actuation Force Study of Next Generation Micro Shutter Array for More Reliable Actuation
Micro shutter array (MSA) is a programmable optical spatial filtering device fabricated by micro electro-mechanical system (MEMS) technology. It was originally developed for James Webb Space Telescope (JWST) to enable multi-object spectroscopy and operated by a moving magnet. Next ... En savoir plus
Plastic Deformation of Metallic Foam
Metallic foams can be plastically deformed to dramatically alter the material’s mass density, microstructure, and bulk mechanical properties. This work investigates the plastic deformation of open-cell aluminum foams numerically, using high fidelity models of metallic foam constructed ... En savoir plus
Silicon Photonic 2 X 2 Power Splitter with S-Bend Configuration
Directional couplers are used for the purpose of redirecting, splitting, and combining light in silicon photonic circuits. They are used extensively in data communication applications such as wavelength-division-multiplexing and signal switching [1]. Their functionality is an integral ... En savoir plus
Mechanical and Thermal Loading of a Composite Gun Barrel
Carbon fiber composites are used across a wide range of industries to provide products with a combination of reduced weight and increased strength. Integration of carbon fiber composites into gun barrels not only offers superior strength, rigidity and lighter weight compared to ... En savoir plus
Characterization of BAW Modes Harmonically Generated (f-2f-3f) in LiNO3 SAW Devices Using COMSOL Multiphysics® Simulation Software
SAW devices, in which acoustic wave travels along the surface of a material, are used as filters, oscillators and delay lines in electronic circuits. However, recent research [1] revealed that bulk acoustic waves (BAW) can be nonlinearly generated in LiNO3 SAW device if the drive level ... En savoir plus
A Mathematical Model of Cerebral Cortical Folding Development
The setup of the problem: To develop a mathematical model of cerebral cortical folding development, half-hemisphere geometry is used and the outer layer (gray matter) is allowed to move inward under the effect of both physical and biochemical factors. The model is time-dependent, ... En savoir plus
An Investigation of Violin Sound Quality through Resonant Modes
This paper describes a simulation study performed with the goal of quantifying the correlation between violin design and sound quality. The investigation first explored the resonant modes of the front plate of a violin by examining its eigenfrequencies. Chladni patterns of increasingly ... En savoir plus
Efficiency and Stability Trade-offs in FSI Simulations of Coronary Artery Blood Flow
Some of the most common fluid-structure interaction (FSI) applications in biomedical research include blood flow in the veins and arteries. COMSOL Multiphysics® simulation software offers two main multiphysics schemes for FSI problems: partitioned (segregated) and monolithic (fully ... En savoir plus
Non-Coiled Spring Optimization Assisted by an Analytical Model
The non-coiled spring, the most ancient and crucial mechanical component, has been widely used in different industry at different scales. During the spring design process, performance, robustness, tolerances, and cost always need to be considered and certain trade-off have to be made. As ... En savoir plus
Effects of Mold-Casting Contact on Solidification in Continuous Casting
This communication describes a model created to investigate the effect of mold-metal contact on casting solidification in the continuous casting process. The Heat Transfer and Solid Mechanics modules of COMSOL Multiphysics® simulation software are used to construct a non-linear finite ... En savoir plus
