Spatially 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 ...

Single crystal aluminum and copper of (001) and (110) 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...
متن کاملNumerical and Experimental Evaluation of Residual Stress and Fatigue Strength of Steel CK35 in Shot Peening Process
In shot peening process the work piece surface is struck by a large number of balls and compressive residual stress is generated on the surface. So, mechanical properties such as fatigue strength, stress corrosion resistance, smooth shape and ... will improve. In this paper, the balls with a speed of 100 to 200 m/s were struck on the steel samples and fatigue strength compared with specimens wi...
متن کاملTensile properties and fatigue behavior of AHSS-DP 350/600 subjected to laser shock processing
This work presents the effects of strain rate on the tensile properties and fracture morphologies of AHSS-DP 350/600 subjected to LSP. Fatigue crack growth test was performed to evaluate fatigue behavior in the metallic plate of AHSS-DP350/600. However, this material is used in automobile industry and enhancing it fatigue resistance is a challenge in material engineering. In order to evaluate a...
متن کاملEffects of simulation parameters on residual stresses for laser shock peening finite element analysis
By using finite element analysis, we proposed an applicable finite element method of laser shock peening (LSP) and discussed various parameters, such as solution time, stability limit, dynamic yield stress, peak pressure, pressure pulse duration, laser spot size, and multiple LSP. The effects of parameters related to the finite element simulation of the LSP process on the residual stresses of 3...
