[ 1 ] - An Upper Bound Solution for Analysis of Twist Extrusion Process with Elliptical Die Cross-section

Twist extrusion process is a rather new route to produce highly strained materials. In this process, severe plastic deformation is applied by large shear strains. In current article, required energy for twist extrusion by use of admissible velocity field together with the upper bound technique is predicted. The proposed model is capable of considering the effect of various parameters such as di...
