Description
This article discussed the influence of pre-cracking on measurement of ceramics Si3N4'SKIC. A new method which is used to make fatigue pre-crack in the specimens made of brittle materials was introduced. Two kinds of three-point-bend specimens were made of the ceramics: the radius of notch of one kind specimens was 0.15mm, the other kind crack was prepared by means of fatigue. The method and its apparatus making fatigue crack is unique, effective, and especially suitable for brittle materials. The KIC value of the ceramics was measured with the two kinds of specimens. It was found that there was only a little difference between KIC values of the two kind specimens calculated with relative data. In addition, results of similar experiment of other brittle materials were introduced to make a comparison. (author)
