107 Development of Small Fatigue Testing Machine using Piezo-electric Actuators
Details
A small fatigue-testing machine that can be set on the stage of an optical microscope simply has been developed to do in-situ observation. This paper introduces it from the following three aspects: (1) the concept about the development of the small fatigue-testing machine, (2) the structure and performance of the testing machine, and (3) results of the experiment showing by micrograph of the fatigue crack in metallic specimen.
