IMPACT DAMAGE ON SILICON-CARBIDE - FIRST RESULTS

This paper deals with the damage of ceramic materials after impact. Th e main information on the phenomenology and the kinetic damage are oft en localized inside the Hertzian cone crack area [1]. With a ceramic t ile target, it is not possible to obtain any information during the te st. Therefore a new geometry of ceramic target, called ''Match'' was d eveloped in order to put crack gauge inside the Hertzian cone. The rel ationship between collected experimental data and microstructural stud ies allow to validate the results of a three dimensional finite elemen t simulation.
