Modeling of multi-edge effects in the case of laser shock loadings applied on thin foils: Application for material characterization of aluminum alloys

This article presents the study of shock wave propagation through aluminum alloys (pure and 2024-T3) produced by laser plasma using experimental numerical tests. Water confinement regime interaction, pulse duration (7.2 ns), power density (1–5 [Formula: see text]) range correspond to peening process configuration parameters. To that scope, we simulate non-linear explicit code LS-DYNA, which validate with results. Thereupon, present a descriptive analysis links separately material model loading conditions dynamic response under high strain rate coupling Johnson-Cook (J-C) Grüneisen equation state (MAT_015 EOS_GRUNEISEN accordingly). In addition, make use stress into target thickness analyze origin different points on Back Face Velocity (BFV) profile during propagation. Finally, provide evidence 2D compressive effects do not depend only focal spot size or such as edge but also initial yield strength.
