DYNAMIC OBSERVATION OF PROPAGATING PROCESS OF CRACKS IN Si_3N_4-BASED CERAMICS
|
Abstract:
A method of dynamic observation of the crack propagation suitable for St,N. and its composites was explored. Applying a limited load on the both ends of a notched beam. the propagating rate of the crack in a sample during 3--point bending can be controlle
