Impact Simulation And Analysis Of Sandwich Structures, Daewon Kim
Impact Simulation And Analysis Of Sandwich Structures, Daewon Kim
Master's Theses - Daytona Beach
Impact damage on aircraft and spacecraft can be a severe problem that may cause catastrophic results. Several aerospace structures have been used to resist or absorb energy in the occasion of impact. Among these, a sandwich structure has advantages with high stiffness, strength to weight ratio, and its relatively cheap cost. However, finding the impact structural response of a sandwich structure, by performing experiments, has disadvantages. First, impact is a complex problem with a multi-parameter nature and many factors should be considered. Secondly, it is a destructive test and the test subject may be damaged during the test. On the …
Development Of A Strain Energy Storage Mechanism Using Tension Elements To Enhance Golf Club Performance, Marc A. Whitezell
Development Of A Strain Energy Storage Mechanism Using Tension Elements To Enhance Golf Club Performance, Marc A. Whitezell
Theses and Dissertations
The development of current golf club designs has followed an evolutionary process starting with the original wooden heads of a hundred years ago, to the thin-walled, hollow body titanium heads of today. Current designs utilize what has become known as the trampoline effect to increase the efficiency of the ball-club impact, which has a number of limiting factors that restrict clubhead performance. These limitations provided the motivation for this research to explore new mechanisms by which the efficiency of the ball club impact could be increased. In particular this research focuses on the development of compliant mechanisms to increase club …

Landfilling is the most common municipal solid waste disposal method in Australia. During the decomposition of the deposited waste, leachate is generated mainly due to the seepage of stormwater through the landfill body.

Weldon School of Biomedical Engineering Faculty Publications
This paper presents a new analysis of the physics of closed head injury caused by intense acceleration of the head. At rest a 1 cm gap filled with cerebrospinal fluid (CSF) separates the human brain from the skull. During impact whole head acceleration induces artificial gravity within the skull. Because its density differs slightly from that of CSF, the brain accelerates, strikes the inner aspect of the rigid skull, and undergoes viscoelastic deformation. Analytical methods for a lumped parameter model of the brain predict internal brain motions that correlate well with published high-speed photographic studies. The same methods predict a …
