 note = {application/pdf, Using a drop hammer apparatus, four kinds of impact compression and forming tests are carried out with nonmetallic materials (i.e., clay, plasticine, silicone polymer and rubber) which have various viscous/elastic/plastic characteristics, and their applicability to the new forming process previously proposed by the authors is discussed. It is concluded that a viscous medium with a high strain rate sensitivity m is advantageous for piercing and shallow stretch-forming. Some new applications (i.e., piercing of small holes and glass sheets) are presented.},
