Abstract: Material parameters of metals and metal alloys are crucial for predictive simulations of the laser peening process, however, the experiments are challenging and the literature often provides conflicting values (for further details see the contribution by dr. Isoz). Here we build on the aforementioned contribution and we perform a sensitivity study of the Johnson-Cook material model parameters. The results are compared to experimental data from the literature, namely backface velocity measurements done using the velocity interferometer system for any reflector (VISAR) and the unknown parameters are identified. Furthermore, we aim to accelerate the parameter identification using model order reduction techniques.
