An Investigation on Force Controlling Method for Measuring Fracture Strength and Toughness of Diamond Film
测定金刚石膜断裂强度及断裂韧性的力控制法研究

The man made diamond film is a kind of high brittle material. For measuring its fracture strength and toughness, a new loading method with force controlling is presented. In the method an elastic pressing head is used to control the rate of loading, and the whole device works smoothly and steadily.
