| Abstract: | This paper presents the preparation method and influential factors in making precraked K_(IC)sample by using TZP ceramic material. A better method of controlling crack growth in a stable manner is introduced. The effects of environment,loading speed,phase transformation toughening of TZP ceramics and residual stress, etc. on measured K_(IC)values by precraked specimens are also analyzed and discussed. The objective of this paper is to develop a new method of engineering application. |
