Modeling Schemes, Transiency, and Strain Measurement for Microscale Laser Shock Peening
In this paper, a coupled modeling scheme, that considered the dynamic evolution of laserinduced plasma and the complete physical interaction between plasma, confined medium, coating layer and the peened metal in laser shock peeing (LSP), is compared with two decoupled modeling schemes, in which shock pressure was first determined and used as loading in subsequent FEM based stress/strain analysi...
متن کاملCharacterization of Plastic Deformation Induced by Microscale Laser Shock Peening
Electron backscatter diffraction (EBSD) is used to investigate crystal lattice rotation caused by plastic deformation during high-strain rate laser shock peening in single crystal aluminum and copper sample on ~11̄0! and (001) surfaces. New experimental methodologies are employed which enable measurement of the in-plane lattice rotation under approximate plane-strain conditions. Crystal lattice ...
متن کاملSpatially Resolved Characterization of Residual Stress Induced by Micro Scale Laser Shock Peening(1501)
Single crystal Aluminum of (001) orientation were shock peened using laser beam of 12 micron diameter and observed with X-ray micro-diffraction techniques based on a synchrotron light source. The X-ray micro-diffraction affords micron level resolution as compared with conventional X-ray diffraction which has only mm level resolution. The asymmetric and broadened diffraction profiles registered ...
متن کاملSystematical Characterization of Material Response to Microscale Laser Shock Peening
The response of materials after microscale laser shock peening (mLSP) was experimentally characterized and compared with the theoretical prediction from FEM analysis in microlength level. Since mLSP is predominantly a mechanical process instead of a thermal process, the characterization focuses on mechanical properties and associated microstructures. An X-ray microdiffraction technique was appl...
متن کاملAbrasive Waterjet Peening with Elastic Prestress: Subsurface Residual Stress Distribution
Recent advances in abrasive waterjet (AWJ) technology have resulted in new processes for surface treatment that are capable of introducing compressive residual stresses with simultaneous changes in the surface texture. While the surface residual stress resulting from AWJ peening has been examined, the subsurface residual stress field resulting from this process has not been evaluated. In the pr...
