Abstract : The finite element approach to structural analysis came into being with large scale scientific computers. Implementation of the finite element approach to structural analysis lagged behind the theory until the release of CRTPLS and NASTRAN in 1970. The release of these programs provided a substantial analytic capability at a low cost. Although there are many technical improvements to come, the primary challange is the effective use of existing capabilities and efficient design of structures. This paper concerns this challenge and how it applies to product engineering of ammunition components.
