Abstract
Friction plays an important role in bulk metal-forming process. Especially, it has an important influence on metal flow in the local loading process. In the present study, the influence of friction on the metal flow in local loading forming process of rib-web component was analyzed by using analytical method, numerical simulation, and experiment. Constant shear friction model was employed in the analytical analysis and numerical simulation. Two kinds of local loading experiment were carried out, which differ in the shape of billet. The results in the present study indicated that (a) in local loading state, increasing friction is beneficial to reduce or avoid the occurrence of shearing deformation behavior; (b) the metal flowing into rib cavity would increase if friction factor increases; (c) as the width of local loading increases or thickness difference of variable-thickness region decreases, the friction effect will reduce.
