✦ Synopsis

An experimental technique has been developed by Arcueil Research and Study Center (CREA) to visualize and follow the evolution of damage in a ceramic during impact. This technique, based on the use of a high-speed camera, allows to obtain qualitative and quantitative information on the damage location and evolution. Experimental data such as crack front velocity, fracture velocity, crack density and time of damage initiation can be obtained. The advantages of this technique are discussed. The experimental set-up and the results obtained by this technique are presented. A numerical simulation is compared with experimental measurements.

AbstractÐThe mechanisms of cyclic fatigue-crack propagation in a grain-bridging ceramic, namely an in situ toughened, monolithic silicon carbide, is examined. The primary goal is to directly quantify the bridging stresses as a function of cyclic loading. To investigate the eect of the number of load
