Download or read book Background for Mechanical Shock Design of Ships Systems written by G. J. O'Hara and published by . This book was released on 1965 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 problems encountered in shock design and analysis of shipboard systems. It discusses: requirements for shock protection, selection of failure criteria, determination of shock environment, development 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.
