Elastic-plastic analysis of tube bending
WebNov 29, 2012 · In our study, an elastic-plastic theoretical analysis is presented to predict the bending moment and springback of bend tube with hollow circular section considering the work hardening in the plastic-deformation region. The FE analysis was performed in order to predict the springback in the conditions of a bend angle in the range of 90 ° to ... WebFigure 1. Analysis diagram of the bent tubes In the process of bending tubes, there are some deformation phenomena such as the tangential elongation and thinning of the outer-wall, the tangential shortening and thickening of the inner-wall and the circumferential distortion of the cross-section. Considering these deformation behaviors, we
