Simulation of Earth Penetration Loads.

Abstract

An experimental apparatus was developed to simulate the impact loads on earth penetrating structures. The device has been built to test 1/4-scale model structures, but the design is suitable for fabrication in a larger size for testing full-scale structures. The device uses the controlled flow of high-pressure explosion product gases acting against a piston to apply either an axial load or combined and lateral loads to a model structure. Loading parameters such as rise time and peak load can be easily varied from test to test by simple adjustments of the device. The technique allows hardwired measurement of the applied load and the response of the structure. A series of initial calibration tests conducted without a model structure indicates that the device operates properly. (Author)
