Leavesley, Peter Joseph (1978). Energy absorbed in impact extrusion. Masters thesis, Aston University.
Abstract
A survey of the literature showed that little had been published on using the extrusion process to absorb the energy of an impact. For the investigation a rig was designed and manufactured and tests were carried out to assess the energy absorption characteristics of various materials when extruded at various reductions of area and at various impact speeds. Some design problems arose from the presence of high transient elastic stress waves. These elastic stress waves also had some effect on the instrumentation.A theory, modified from a standard theory, makes allowances for the kinetic forces present in the various components at any instant during the extrusion. The theory always predicted a lower extrusion pressure than that measured experimentally.
