Laser Shock Peening (LSP) is an advanced technique for enhancing surface properties, drawing significant interest its ability to induce beneficial residual stresses in materials. Traditional LSP design processes, reliant on manual parameter selection, often result imprecise control over the stress distribution, necessitating multiple iterations and high costs. This study introduces a machine learning (ML)-based approach, utilizing Random Forest (RF) algorithm, automate optimize of parameters nickel-aluminium bronze surfaces. Our findings demonstrate RF model's capability accurately predict distributions, achieving compressive up 472 MPa with notable reduction iterations. The model forecasts both uniform non-uniform patterns, particularly identifying areas susceptible Residual Stress Holes (RSH) improved precision. With Absolute Percentage Error (APE) only 6.2 %, our approach significantly outperforms traditional ML algorithms, offering novel method efficiently designing complex fields applications.
