Plasticity analysis of pure aluminium extruded with an RBD palm olein lubricant
In this study, a cold-work plane strain extrusion apparatus was used to perform plasticity analysis of a work piece that was extruded using RBD palm olein as a cold metal forming lubricant. The experimental apparatus consists of a set of two taper dies with 45-degree die half angles and a billet (wo...
