Experimental and numerical studies of crack initiation due to liquid jet impacts

Résumé

Damage initiation provoked by liquid impacts on a typical brittle ceramic is experimentally and numerically studied. A test bench has been designed and manufactured for this purpose. It produces series of water jet with known shapes and velocities that impact a sample on a specified location. Liquid jets are produced by cutting a cylindrical continuous water jet with a disk turning at high speed (up to 2000 rpm). Tests are carried out to get a better understanding of crack initiation mechanisms under this specific dynamic loading. Thanks to a comparison between numerical simulations (both fluid and solid) and experimental results, various damage initiation models can be evaluated and validated.
