Research on Cold Roll Forming Process of Strips for Truss Rods for Space Construction.

As shown in Figure 11 and Figure 12 , the stress–strain histories of nodes 48594 and 15928 are similar, the two nodes are located in the inside of the bending corners, and in the process of deformation, with the increase in the number of forming passes, their equivalent stresses show an increasing trend during the action of each group of rollers.

It can be seen from Figure 16 that the peak longitudinal strain at different roll spacings shows a decreasing trend as the number of passes increases.
