FR-6267, NRL FORMAL REPORT: BACKGROUND FOR MECHANICAL SHOCK DESIGN OF SHIPS SYSTEMS (12-MAR-1965)

FR-6267, NRL FORMAL REPORT: BACKGROUND FOR MECHANICAL SHOCK DESIGN OF SHIPS SYSTEMS (12-MAR-1965)., This report has been prepared to describe some of the progress made since World War II in the several areas related to the complex set of pi-oblems encountered in shock design and analysis of shipboard systems. It discusses: requirements for shock protection, selection of failure criteria, determination of shock environment, detelopment of analysis and design procedures, results from past research and engineering, and the needs for future research and engineering. Essentially it sketches the evolution from the simple shock design number concept, which is limited, to a more rational approach which can allow the shock design-analysis of unprecedented equipment.
