Influence of Crack Path on Crack Resistance of Brittle Matrix Composites

January 1, 2001
Author(s)
S Wu, D Patterson, M Ferber, Lin-Sien H. Lum
Studies on particulate reinforced ceramic composites, mainly glass/Al 2O 3, have shown pronounced crack path variations with variations in microstructure and loading rate. The variations in path strongly influenced the crack resistance of the composite

Information Technology Measurement and Testing Activities at NIST

Michael D. Hogan, Lisa J. Carnahan, Robert J. Carpenter, David W. Flater, James E. Fowler, Simon P. Frechette, M M. Gray, L A. Johnson, R. McCabe, Douglas C. Montgomery, Shirley M. Radack, R Rosenthal, Craig M. Shakarji
Our high technology society continues to rely more and more upon sophisticated measurements, technical standards, and associated testing activities. This was true for the industrial society of the 20th century and remains true for the information society

Infrared Spectra of Ne, Kr, and Xe

January 1, 2001
Author(s)
Craig J. Sansonetti, M M. Blackwell, Edward B. Saloman
New observations of the spectra of neutral Ne, Kr, and Xe in the region 0.7 to 5.0 m with the 2-m NIST FTS provide precise new wavelengths and resolve questions concerning lines that were previously multiply classified.

Input Data for Multizone Airflow and IAQ Analysis

January 1, 2001
Author(s)
Andrew K. Persily, E M. Ivy
The use of multizone airflow and contaminant dispersal models requires a range of data. In terms of airflow analysis, these data include leakage characteristics of airflow elements, wind pressure coefficients, ventilation system characteristics such as
