ON THE EFFECTS OF STRESS-WAVE DIFFRACTION ON GROUND-SHOCK MEASUREMENTS: PART I,
Abstract
This memorandum presents an exact solution of the response of a rigid spherical object (inclusion) embedded in an elastic medium subjected to ground shock. The Fourier-transform method was used to determine the transient response of the spherical inclusion. It was found that the inclusion motion differs substantially from the free-field motion, both in acceleration and velocity. A slight change in displacement was also ob served. The effect of geometry on the response of an inclusion was also investigated briefly. It was shown that the frequency response of a cylindrical inclusion is quite similar to that of the spherical inclusion. On the basis of these study results, it is believed that a substantial error could occur in shock measurements due to stress-wave-diffraction phenomena. (Author)
