Displacement Uncertainty in Interferometric Radius Measurements

January 1, 2002
Author(s)
William T. Estler, Tony L. Schmitz, Angela Davies, Christopher J. Evans
Interferometric radius measurements may be completed using a radius bench, where radius is defined as the displacement between the confocal and cat''s eye nulls (identified using a figure measuring interferometer). Measurements of a Zerodur sphere have

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
