  • Tension test for alumina ceramic materials using open

    2017-12-27 · The test system is suitable to perform both the open-loop and closed-loop tests for the ceramic material even when system noise exists. However, when there is very little displacement to be measured, the noise becomes a problem. Based on the previous measurement and analysis of system noise, further improvement of the testing system can be made by increasing the system’s stiffness …
