摘要：

The analysis of strength degradation in the preceding paper is here extended to tempered surfaces. Addition of a surface compression term to the indentation fracture equations leads to simply modified degradation relations. Impact energy is again identified as the important service variable in degradation. Comparative strength tests on thermally tempered and annealed glass disks after impaction with SiC particles confirm the predicted energy dependence of strength loss. The results indicate that surface‐strengthening processes can be just as effective in improving resistance to strength degradation as can increasing toughness. However, improvements in surface erosion resistance are relatively insignificant. Copyright © 1979, Wiley Blackwell. All rights reserved
