A Study of New Parameters Effect on the Springback of Aluminum Sheets in Plane Strain Bending

Fathi Al-shamma | Hajer M. Issmael

Abstract: In this study a theoretical and experimental analyses of the effect of different parameters on Springback in wide and narrow plate was done for three types of Aluminum alloys: 1100, 5083 and 6061. The study investigated in the effects of material type, plate width and bending angle on springback in narrow and wide plate of Aluminum. In other hand study presented the effects of theses parameters in residual stresses. Experimental part including finding residual stresses and springback. Theoretical part including using analytical equation to calculate strain total and strain final using flow equation of Levy-Mises in order to find springback and residual stresses. Grid deformation theory used to find strain in plate. All equations processed using MATLAB program. Numerical analysis including using both SOLID WORK and ANSYS 18.2 for designing and simulation of bending process to calculate residual stresses. X-ray diffraction method also used to find the amount of residual stresses in all specimen. The results show that the springback amount effected by the variation in material types and material width more than the effect of angle of bending. Numerical and experimental results were compared which gives good agreement.
