Determination of Dynamic Fracture Toughness of Si3N4 Ceramics by Instrumented Impact Test

Abstract:

Article Preview

The current paper give a brief overview over the principle and information content of the instrumented impact test completed by electro-emission measurement. Introducing over experiences taken by applying these test on a high-tech SiAlON ceramic a novel method for the determination of the dynamic fracture toughness of silicon nitride ceramics is suggested.
