The aluminum alloys have low density, relatively high strength, and high strength-to-weight ratio, which brings some major advantages in marine structure design, fabrication, and operations. However, marine ships are subjected to a complex and severe loading, and the typical failure mode of aluminum under extreme dynamics loading such as wave slamming and high velocity impact is ductile fracture. ...

Research is proposed for the development and implementation of state of the art computational and experimental tools for the investigation of the impact of control surface freeplay on the flutter and limit cycle oscillation characteristics of two-dimensional and three-dimensional wings in subsonic and transonic flow. Highly efficient and accurate aeroelastic simulation tools will be constructed ba ...

This Small Business Technology Transfer Phase I project is aiming at developing and implementing a multiscale composite model to predict the ceramic matrix composite (CMC) response to the impact loading by foreign objects. In particular, the physics-based model will be applied to describe the multiscale foreign object damage (FOD) phenomena of CMCs due to the complex nature of impact dynamics coup ...

Turbine disks are amongst the most critical components in aero- and naval-vessel engines. They operate in a high pressure and temperature environment requiring demanding properties. Nickel-based supperalloys which have high creep and oxidation resistance at high temperatures are widely used as the material of turbine disks. The elevated-temperature strength of this supperalloy and its resistance t ...

A novel method of fabricating carbon nanotube (CNT) reinforced polymer matrix composites is proposed. It includes growing super-aligned carbon nanotube arrays on a flat substrate, using NCSU proprietary shear pressing method to compress the grown arrays into a layer of densely packed, highly aligned CNTs inclined at an angle of several degrees to the substrate, separating the produced CNT sheet fr ...

The objective of this proposed effort is to leverage state-of-the-art modeling and simulation tools to predict and assess the performance of a novel layered material system as protection for high-value missiles when deployed in launchers and canisters. The physics-based computational tools developed and used by Corvid allow for complex material interactions to be captured to provide an understandi ...

The objective of this proposed effort is to continue the development of Corvid’s existing modeling and simulation framework to provide an innovative methodology used to predict the response of full-scale weapons systems to fast cook-off (FCO) and slow cook-off (SCO). Ammunition presents a special problem where no reliable and inexpensive sub or small scale testing capability has been identified. ...

A great deal of research has been done on thin film Carbon Nanotube Transistors. Single Walled Carbon Nanotubes (SWNTs) have exceptional electrical properties, High speed circuits require high carrier mobility, and individual SWNTs have a carrier mobility of up to 120,000 cm2/Vs and can be doped n and p-type. Enriched semiconducting SWNTs (s-SWNTs), narrowed down to individual chiralities provid ...

Benthic microbial fuel cells (BMFCs) are bio-electrochemical power sources that derive fuel from renewable detritus. They have the potential to be cost-effective, sustainable energy sources to power remote, widely distributed instruments for oceanographic, environmental and biological monitoring. Currently, low power density limits their usefulness and cost-effectiveness. The objective is to devel ...

Wave Computation Technologies and Duke University will develop minimally coupled, co-mingled E and B field antennas through numerical and experimental investigations based on both phenomenological and first-principle theories. The project objectives are to (a) develop the simulation capability for modeling superconducting quantum interference filter devices and the related B field antennas, (b) ma ...
