The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...
The ability to engineer stiffness and strength in any desired direction make composites an ideal material candidate for various applications when compared to their traditional isotropic counterparts. In spite of this, the ability to model the material response in composites has yet to be fully explored. Composite research largely focuses...
Simulation models were developed to explore the reversible nature of gecko dry
adhesion system. The central idea of this model is that even with a small moment imparted on the contact tip, the seta can be easily ad-adhered. It is shown that this contact condition is very sensitive, but can...
Augered cast-in-place piles, also known as ACIP piles, have been used for more than
seven decades in the United States and have gained in popularity due to their relatively
quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring
environment as compared to some other deep foundation installation...
A test system was developed and used to
investigate ice/structure interaction with centrifugal
modeling. The test system was designed to perform two
main functions: (1) create a uniform ice sheet, and
(2) drive a model structure through the ice sheet at a
constant speed. Both of these functions were required...
The objective of this study was to compare light wood framing and traditional timber
framing quantitatively through environmental impact assessment and load path analysis. This
research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and
the design of structures considered within reflect the general characteristics...
In this paper, a numerical method is used to predict
the response of an elastic body during a collision in which
both normal and tangential impulses are important. Results
are compared with those from simplified prediction
procedures, which stem from the assumptions that the energy-returning
capacity of the normal deformation...
Even though the elastic deformations that occur during the
impact of colliding bodies may be small in comparison to their actual
dimensions, they play an important role in mechanical collisions.
During the time the bodies are in contact, elastic, friction, and inertia
properties combine to produce a complex variation of...
