Optimized upper bound analysis of polymer coated metal rod extrusion through conical die
… process. In the present research study a new upper bound analytical model is developed to predict the forces required to conduct extrusion of a polymer coated metal rod successfully. The search for the lower upper bound power functional is modeled as a non linear optimization problem. …

Modelling the Extrusion of a Hard-Metal Paste
… An analytical model was developed using an upper bound method following the work of Khoddam et al. (2011a, b). Benbow-Bridgwater (1995) constitutive and friction parameters were used. Experiments were performed with 3D printed and machined dies for MCC/CaCO3 and WC-Co, respectively. For both …
