Carey, Jason P., Melenka, Garrett W., Cheung, Benjamin K., Lepp, Eric
Two dimensional (2D) tubular braided composites consist of textile fibers imbedded in a resin matrix. Braid geometry and void content will affect the mechanical behavior of the tubular braided composite samples. In this study, tubular braid samples were assessed using micro X-ray computed...

Impact Failure of Planetary Materials: Lateral Field Ejecta Measurements using Particle Image Velocimetry
Download2014
Schneider, Markus, Spray, John, Rogers, Robert, Hogan, James, Vincent, Gregory
The dynamic fragmentation of a fine grained granitoid material has been examined. Target thicknesses ranged from 7 to 40 mm and impact energies from 12 to 2,500 J. Combined particle image velocimetry and image enhancement techniques are introduced and have been used to measure the size and...

Lamberson, Leslie, Pagano, Steven, Hogan, James
The rate-dependent compressive response and resulting fragmentation characteristics of dry ox cortical bone and cyanoacrylate-based cortical bone surrogate material was investigated in two material orientations. Tests were conducted under quasi-static (10−3 s−1) and dynamic (103 s−1) loading in...

The effect of perturbations on resistance to sliding in second order moments comparing two different bracket types
Download2014
Wong, Justin W., Carey, Jason P., Romanyk, Dan L., Heo, Giseon, Toogood, Roger W., Major, Paul W.
Orthodontic literature has shown all ligation methods to behave similarly in the clinical situation; however, the reasoning behind this still requires further investigation. A novel frictional device able to measure forces at the level of the bracket along with a custom perturbation device was...

Density Conversion Factor Determined using a Cone-Beam Computed Tomography Unit NewTom QR-DVT 9000
Download2006
Carey, Jason, Lagravère, Manuel O., Major, Paul W., Fang, Y., Packota, Garnet V., Toogood, Roger W.
Objective: The purpose of this study was to determine a conversion coefficient for Hounsfield Units (HU) to material density (g cm−3) obtained from cone-beam computed tomography (CBCT-NewTom QR-DVT 9000) data. Methods: Six cylindrical models of materials with different densities were made and...

We examine the transient evolution of a negatively buoyant, laminar plume in an emptying filling box containing a uniform porous medium. In the long time limit, the box is partitioned into two uniform layers of different densities. However, the approach towards steady state is characterized by a...

A new ductility exhaustion model for high temperature low cycle fatigue life prediction of turbine disk alloys
Download2011
Zhu, Shun-Peng, Sun, Rui, Zuo, Ming J., Li, Haiqing, Huang, Hong-Zhong
Based on ductility exhaustion theory and the generalized energy-based damage parameter, a new viscosity-based life prediction model is introduced to account for the mean strain/stress effects in the low cycle fatigue regime. The loading waveform parameters and cyclic hardening effects are also...

Ma, Y., Flynn, M.R. and B.R. Sutherland
We experimentally investigate the behaviour of a line-source plume falling through a finite two-layer stratified ambient where the depth of the upper ambient layer increases in time. Laboratory observations suggest one of two possible flow regimes depending on the value of 𝜆 , which represents...
