Michigan Technological University is collaborating with Southwestern Energy and REL Inc. to develop and integrate a compressed natural gas (CNG) matrix tank that enables efficient packaging, increases range, and reduced cost for CNG vehicle applications. The vehicle being used in this project is a light-duty pickup truck to take advantage of the open space underneath the body and bed of the vehicle. With today’s cylindrical CNG tanks consuming cargo space, a solution is to develop a tank capable of being shaping to the underbody of the truck to free cargo space. University faculty and graduate students utilizes Finite Element Analysis …

Methodology For Analyzing Epoxy-Cnt Phononic Crystals For Wave Attenuation And Guiding, Madhu Kolati
Dissertations, Master's Theses and Master's Reports
Phononic crystals (PhnCs) control, direct and manipulate sound waves to achieve wave guiding and attenuation. This dissertation presents methodology for analyzing nanotube materials based phononic crystals to achieve control over sound, vibration and stress mitigation. Much of the analytical work presented is in identifying frequency band gaps in which sound or vibration cannot propagate through these PhnCs. Wave attenuation and mitigation analysis is demonstrated using finite element simulation. Engineering principles from current research areas of solid mechanics, solid-state physics, elasto-dynamics, mechanical vibrations and acoustics are employed for the methodology. A considerable effort is put to show that these PhnCs can …
