Compensating Gravity Effects in 1-G Small-Scale Structural Modeling
Abstract
This report presents the results of a study to develop viable concepts to compensate for the gravity effects in 1-g small-scale tests. These tests simulate the effects of nonnuclear weapons on protective structures. Two viable concepts associated material preparation procedures were developed on the basis of theoretical and experimental evidence governing equations, similarity requirements, and known material behavior. Although Phase II work is necessary to demonstrate the viability of the developed concepts, no major obstacles to the success of these concepts are apparent. The first concept is applicable to close-in blasts where the effects of gravity are likely to be insignificant. The second concept was developed for general application and can compensate for gravity effects regardless of significance. Preliminary planning for the Phase II scope and work plan is also included in this report. The successful completion of the Phase II program would culminate in the development of a powerful and economic means to provide necessary data in establishing improved design and upgrade methodologies for protective structures subjected to nonnuclear weapons attacks. Keywords: Gravity effects; Simulants; Weapon effects; Structural modeling; Small scale structures; Similarity.
