Effect of Thermal Cycling on Whisker-Reinforced Dental Resin Composites

January 1, 2002
Author(s)
H H. Xu, F Eichmiller, Douglas T. Smith, Gary E. Schumacher, Anthony A. Giuseppetti, Joseph M. Antonucci
The mechanical properties of dental resin composites needs to be improved in order to extend their use to high stress-bearing applications such as crown and bridge restorations. Recent studies used single crystal ceramic whiskers to reinforce dental

Elastic Properties of Model Random Three-Dimensional Open-Cell Solids

January 1, 2002
Author(s)
A P. Roberts, Edward Garboczi
Most cellular solids are random materials, while practically all theoretical structure-property relations are for periodic models. To generate theoretical results for random models the finite element method (FEM) was used to study the elastic properties of

Energy Dispersive X-ray spectromety by Microcalorimetry for the SEM

January 1, 2002
Author(s)
Dale E. Newbury, David A. Wollman, Sae Woo Nam, Gene C. Hilton, Kent D. Irwin, John A. Small, John M. Martinis
Analytical x-ray spectrometry for electron beam instruments has been significantly advanced with the development of the NIST microcalorimeter energy dispersive x-ray spectrometer (mcal EDS). The mcal EDS operates by measuring the temperature rise when a
