Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration of the orthodontic torque simulator. The orthodontic torque simulator was coupled with a...

By adapting the Föppl-von Kàrmàn equation, which describes the deformation of a thin elastic membrane, we present an analysis of the buckling pattern of a thin, very viscous fluid layer subject to shear in an axisymmetric geometry. A linear stability analysis yields a differential eigenvalue...

Dynamic Fragmentation of Planetary Materials: Length Scale Quantification and Semi-Analytical Modelling
Download2013
Rogers, Robert, Spray, John, Hogan, James
The dynamic fragmentation of planetary materials during impact into finite targets has been examined. A particle tracking algorithm was implemented to estimate the size and velocity of fragments ejected from the rear of the target. A total of 76 experiments were performed for four material,...

The design and testing of an orthodontic torque simulator that reproduces the effect of archwire rotation on orthodontic brackets is described. This unique device is capable of simultaneously measuring the deformation and loads applied to an orthodontic bracket due to archwire rotation. Archwire...

Automated Microscopy and Particle Size Analysis of Dynamic Fragmentation of Natural Ceramics
Download2013
Castillo, Josemar, Rogers, Robert J., Rawle, Alan, Spray, John, Hogan, James
The dynamic fragmentation of gabbro and granitoid tiles, and coarser and finer grained granitoid blocks have been examined for impact energies of 21–6180 J. Intra-grain fragmentation and inter-granular frictional melting were observed to be common features of the fragmentation process....

A tubular braided composite bone cast for improving the efficiency and quality of bone fracture treatment is investigated. Finite element analysis was used to evaluate stress concentrations in fracture sites supported with plate and tubular casts. The stress in a plated bone is 768 % of that in a...

Lagravère, Manuel O., Carey, Jason P., DeCesare, Alessandro, Secanell, Marc
The purpose of this study is to minimize errors that occur when using a four vs six landmark superimpositioning method in the cranial base to define the co-ordinate system. Cone beam CT volumetric data from ten patients were used for this study. Co-ordinate system transformations were performed....

Dynamic Fragmentation of Planetary Materials: Sub-Hypervelocity Ejecta Measurements and Velocity Scaling during Impact Testing
Download2013-01-01
Hogan, James, Vincent, Gregory, Spray, John, Rogers, Robert, Schneider, Markus
Ejecta velocity measurements were made during impacts into solid planetary materials. Ejecta velocity fields overlie each other when normalized by vmax, v50%mass, and v50%KE; these correspond to the maximum velocity and median values of mass and kinetic energy among ejecta velocities....

Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine...
