Abstract:This parametric study uses a hydrocode to explore the effects of varying several dimensions and properties of dynamic tensile extrusion (DTE). A comparison is made to published data for the material models used. Then variations in the geometry of an extrusion die and properties of the projectile are examined. Comparisons are made regarding the peak and downrange velocities as individual DTE components are modified.
