Deep-Penetrating Conical Cracks in Brittle Layers from Hydraulic Cyclic Contact

January 1, 2005
Author(s)
Yu Zhang, Jun-Feng Song, Brian R. Lawn
A study is made of fracture from cyclic loading of WC spheres on the top surfaces of thick (1 mm) brittle layers on polymeric substrates, as representative of repetitive occlusal contact on dental crown structures. The advantage of glass layers is that

Development of a Microfluidic Rheometer for Complex Fluids

January 1, 2005
Author(s)
Jai A. Pathak, Robert F. Berg, Kathryn Beers
Our group has recently published a report of a combinatorial rheometer/viscometer developed in our lab, based on the princinple of a damped harmonic oscillator. In this paper, we describe a modification of this approach to scale down this viscometer to the

Discrete Combinatorial Investigation of Polymer Mixture Phase Boundaries

January 1, 2005
Author(s)
J Cabral, Alamgir Karim
We report a combinatorial approach for mapping bulk polymer mixture phase behavior. The technique consists of a parallel cloud point detection scheme using discrete composition libraries, which are scanned across a temperature range and optically imaged
