Reduction of Stresses in Buried Structures

Abstract

Tests were performed in Event DIAL PACK on 1- and 3-foot diameter steel cylinders with hemispherical end caps to obtain information on the dynamic behavior of structures containing fluid (a) internally pressurized and (b) with backpacking. The four test structures were oriented with their longitudinal axes parallel to the surface and normal to a radius through ground zero. The data were used to compare the variation of the parameters of internal pressurization and backpacking and to check the results of a two-dimensional, nonlinear, large deformation computer code developed for this task. The 3-foot diameter models were designed according to the recently developed optimization equations by NCEL.
