Earliest Evidence of Human Activities on Northern Tibetan Plateau

The use of nondestructive evaluation (NDE) to predict strength or reliability of materials requires two steps. One is to identify and measure the dimensions of strength-controlling defects, and the other is to relate the defect size to the strength. The purpose of this paper is to examine such relations between defects and strength for ceramic fiber composites, and to identify some of the important flaws for which nondestructive detection methods will be needed
