Grahic Jump Location
Description of laser-peening process: (a) workpiece is covered with a protective ablative layer and an inertial confinement layer, a pulsed, high-energy laser is fired at the part, and (b) a region of high-pressure plasma is generated, which causes a shock wave to travel through the material.
Grahic Jump Location
Geometry of 33 mm thick butt-weld specimen (laser-peened area shaded)
Grahic Jump Location
Contour method principle: (a) a body containing unknown residual stress is cut in half, (b) the free surface deforms as the stresses normal to the plane of the cut are released, and (c) applying the opposite of the deformations back to the part recovers the initial residual stress state.
Grahic Jump Location
Finite element model of half of the sample weld specimen
Grahic Jump Location
Experimentally measured strain data and strain fit for specimen 10-02
Grahic Jump Location
Residual stress versus depth for laser peening parameter study: (a) effect of number of layers on residual stress state and (b) effect of irradiance on residual stress state
Grahic Jump Location
Sample of a measured surface line trace from each half of the cut (as-welded specimen) with fits to each surface shown along with the average of both fits: (a) line trace along x=102 mm and (b) line trace along y=16.25 mm
Grahic Jump Location
Final CMM surface (after fitting, and averaging) interpolated at finite element node locations and inverted (for clarity): (a) as-welded weld and (b) laser-peened weld (laser peening applied along y-min surface from x=50 to x=150)
Grahic Jump Location
Contour plot of residual stress distribution across the plane of the sample weld: (a) before laser peening treatment and (b) after laser-peening treatment on bottom surface
Grahic Jump Location
Line plots of residual stress and distribution before and after laser-peening treatment: (a) center of weld bead, (b) weld bead toe (9 mm from center), and (c) outside of weld (30 mm from center)
