Nanoindentation Test and Stress Fields Simulation of Hot-Pressed Silicon Nitride Ceramic

Abstract:

In order to investigate material properties of silicon nitride ceramic, nanoindentation tests are carried out on Hot-press silicon nitride specimen. The micro-hardness and elastic modulus are obtained. simultaneously, load-displacement curve is acquired. The whole process is simulated in ansys. Through comparing, there are satisfactory consistency between experimental curve and simulation curve. In addition, simulation can also indicate the distribution of stress fields during loading and unloading process. Base on these informations, the mode of cracks development and mechanism of material removal can be known.
