Book excerpt: Laser driven shockwaves are currently being used in an assortment of industrial applications and physics research. Although used in many studies, one of the most common and successful industrial applications is the process of laser shock peening (LSP). LSP has been a developing field of study since the 1970’s but only experienced commercial success in the early 2000’s. Despite the relatively long history, the physical impulses created by the process have been infrequently and incompletely investigated. This study was constructed to investigate the impulse loads created across the LSP tradespace parameters and evaluate how industry can better analyze LSP parameters and utilize the data in their own optimization. Using photon doppler velocimetry, peak pressures and magnitudes generated by LSP conditions are evaluated in titanium and aluminum alloys in this study. The studies are extended to be inclusive of opaque overlays on the target materials that act as thermal barriers and also modify the pressures generated. This data is critical to understanding and optimizing the LSP process for different material applications and LSP treatment purposes and has not been comprehensively investigated prior to this work. Extension of the pressure data to physical treatments was validated through measurements of residual stress with x-ray diffraction and simulation of the process with finite element simulations. Finite element studies were also used to define the converged boundaries for the newly defined impulse parameter space and demonstrated prediction of residual stresses in comparison to experimental datasets. Results of these studies are expected to provide additional understanding of the LSP process for both industrial use and extension to optimization studies of LSP treatments. It is the intent of these cumulative studies that a more thorough detailing of LSP impulse and simulation capabilities are available for those interested in evaluating the process.
