IMPROVED METHODS FOR THE APPROXIMATE PREDICTION OF LARGE DEFORMATION OF ICBM STRUCTURES FOR USE IN LETHALITY ANALYSIS. VOLUME I.
Abstract
The general problems confronting the structural analyst who is concerned with the lethality of an ABM are discussed. Possibilities of synergistic structural response effects tending to enhance or degrade damage are pointed out. A review of the state of the art pertinent to the problem is included, which pinpoints the importance of the finite difference elastic-plastic codes developed at MIT. The mechanics of a free ring are summarized to clarify the energy balance. The results of a limited parametric study on rings are applied to finite cylinders with free ends and to finite cylinders with clamped ends. An approach is indicated which will permit extrapolation of these techniques to prediction of structural response of conical shapes and more realistic RV structures. The objective of the effort is to develop and justify basic techniques for analysis of RV structural response to multiple (or single) dynamic impulsive loads which might occur under the effects of nuclear weapon detonations. Direct application of these techniques to specific ABM engagement problems is classified, and is hence not included in the present document.
