Stress Corrosion of Ceramic Materials.
Abstract
A film deposition and surface analysis system has been set up. This system will be used for the analysis of the effect of stress on chemical reactions of ceramics with environments such as water. Preliminary results of Raman spectroscopy experiments suggest that there is an increase in the number of defects in the structure of fused silica under stress. A model describing the effect of water diffusion controlled crack growth has been derived. It was shown that the presence of a relatively K sub I independent region of crack growth has a significant effect on proof testing. (Author)
