Using a rubber propelled press that passed through the press guide and directly impacted on the face of the powder in a die. The velocity of the press was controlled by changing the number of rubber bands. Using an acryl plate of appropriate strength, an author observed the progression of both the press and the shock wave that were produced. On the theoretical calculations an author overlooked the elastic recovery factor; the effect of the kinetic state of powder and the friction between the powder and die wall; the effect of the air that was mixed with the powder particles. On both experimental and theoretical calculation the final density and shock wave velocity were examined.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理工学部"},{"subitem_1522300295150":"en","subitem_1522300316516":"Science and Engineering Division, University of the Ryukyus"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/26600"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0387-429X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250785"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理工学部紀要. 工学篇"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of Science & Engineering Division, University of the Ryukyus.
