Crack Growth Threshold in Soda Lime Silicate Glass: Role of Hold-Time

February 1, 2003
Author(s)
J -. Guin, Sheldon M. Wiederhorn
Atomic force microscopy was used to examine the shapes of cracks and residual features left behind on the fracture surface after holding cracks at a stress intensity factor below the fatigue threshold for soda lime silicate glass. After propagating a crack

Distinguishing the Relative Contribution of Fossil Fuel and Biomass Combustion Aerosols Deposited at Summit, Greenland through Isotopic and Molecular Characterization of Insoluble Carbon

September 1, 2002
Author(s)
J F. Slater, Lloyd A. Currie, J E. Dibb, Bruce A. Benner Jr
Although the earth's polar regions are isolated from most industrial activity, combustion-generated particles from both fossil fuel and biomass burning impact the regions. Most efforts aimed at quantifying the input of combustion aerosols at Summit
