The influence of curvature on FLC’s of mild steel, (A)HSS and aluminium
نویسنده
چکیده
In literature the influence of curvature on formability has been reported. This paper shows results for four materials when an FLC is measured with increasing curvature. It shows the FLC increases for sharper curvature most notably with 20 [mm] tool diameter. The increase is negligible on the left hand side, moderate on the right hand side and large on the plane strain axis. It is thought that contact pressure plays a role here and preliminary simulations indicate that this is quite possible.
