Application of the 3D Digital Image Correlation to the Analysis of Deformation of Joints Welded With the FSW Method After Shot Peening

Abstract: The three dimensional Digital Image Correlation (3D DIC) method is used for measurements of deformations and displacement in plane elements exposed to loading. The paper presents the experimental tests of an application of the ARAMIS system to the analysis of deformation of joints welded with the FSW method after shot peening treatment. The butt joints were made of 2024-T3 aluminum alloy sheets with the thickness of 1 mm, which next were peened with glass beads about granulation in range 500 ÷ 900 µm. Tests of… Show more

“…The frictional heat, generated between the bobbin tool and the workpiece softens the material to a plasticized flow [6,7] which is mixed by the stirring action between the advancing side (AS) and the retreating side (RS) of the rotating tool [8]. The stir-related plastic flow around the pin can also be vertically squeezed at the sub-shoulder regions of the tool [9,10], restricted by the top and bottom shoulders [11][12][13]. By advancement of the tool through the weld-line, the combination of these flow regimes deposits the stirring zone (SZ) region at the trailing edge of the tool [14].…”

“…Materials 2020, 13, x FOR PEER REVIEW 7 of 18 explained by the high thickness of the workpiece (5 mm), which often results in the highest values of joint efficiency [2]. The digital image correlation technique provides more details about welded specimen behavior during the tensile test [42,43]. The obtained strain maps resulting from the DIC measurement for five points marked on the curve (Figure 7) are presented in Figure 8.…”
