Use of a macroscopic model for describing the effects of porosity on shock wave propagation
Abstract
Materials are manufactured by sintering involve porosity. Some material processes, like laser peening, consist in applying shocks onto the surface of a porous material surface to induce permanent densification that will increase its resistance to corrosion and wear. An estimation of the residual compaction and stresses within the material after treatment requires a good knowledge of shock wave propagation in such media. To investigate the effects of porosity on this propagation, we have performed velocity interferometer system for any reflectors measurements on laser shock-loaded samples of sintered steels with 10%−28% porosity. The records do not agree with the predictions of a simple P−alpha model from the literature. Hence, a formulation of the compaction process is proposed to improve the correlation between experimental and simulated velocity profile.
