This Annual Report summarizes the progress that has been made during the first year of the two-year grant from the Office of Naval Research. The dynamic behavior of structures subjected to mechanical shock loading provides a continuing problem for design engineers concerned with shipboard foundations supporting critical equipment. There are two particular problems associated with shock response that are currently under investigation. The first topic explores the possibilities of developing a transient design analysis method that does not degrade the current level of the Navys shock-proofness requirements for heavy shipboard equipment. The second topic examines the prospects of developing scaling rules for the shock response of simple internal equipment of submarines subjected to various attack situations. This effort has been divided into two tasks chemical explosive scaling for a given hull and scaling of equipment response across different hull sizes. The computer is used as a surrogate shock machine for these studies. Hence, the results of the research can provide trends, ideas, suggestions, and scaling rules to the Navy. In using these results, the shock-hardening program should use measured data rather than calculated data.
