This paper deals with the spallation induced by shock wave propagation in targets during the laser shock peening process. Physical aspects concerning laser-matter interaction, shock wave propagation, and spallation are considered. A continuous kinetic model for the spallation process is included in a one-dimensional finite difference hydrodynamic code using Lagrangian coordinates in order to calculate the laser-induced spallation phenomena. Shock wave propagation in solids is calculated and validated by experimental data. The spallation zone location is then calculated for various materials with different thickness of foils and various laser shock peening parameters. The numerical simulations are compared with previously reported experimental results, and good agreement is obtained for the spallation threshold and damage zone location.

Wall Thinning

Adhesion strength of oxide layer formed on carbon steel in air at elevated temperature was evaluated using a laser shock method to reveal the influence of the oxide layer on the wall-thinning behavior caused by liquid droplet impingement. The strength of the interface between magnetite and the carbon steel was comparative to the yield stress of the steel or less. It was suggested that formation of the oxide layer reduce the critical velocity, which might result in exfoliation and wall-thinning, compared to without oxide layer.
