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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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, ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More
