EXPERIMENTAL STRESS ANALYSIS OF OVERPRESSURE FACILITY FOR PROJECT HEST II, MINUTEMAN MISSILE SITE D-1.
Abstract
Stress data were obtained during a surcharge loading of the HEST II overpressure facility. The two objectives accomplished were the control of the surcharge loading and an evaluation of the load-carrying capacity of the facility. The behavior of the structure was determined during the surcharge loading using the strain gage technique and observing the stress-strain relationships. A preliminary qualitative analysis was made to determine the structure mode of failure. Stress-strain relationships in the elastic range were obtained by analytical methods. Specimens were taken from each structural member at locations of anticipated maximum stress. Uniaxial tensile tests were conducted on these specimens to determine the characteristic stress-strain curve of each material. The main function of the facility was to resist loads that were applied to it. Although the facility experienced some localized yielding, there was no structural damage. Apart from tabulated results, the report includes a general discussion and other pertinent background material to acquaint the reader with the techniques used to obtain the stress information and to achieve the required objectives.
