THE EFFECT OF STRESS-WAVE DIFFRACTION ON STRESS MEASUREMENTS AND A CONCEPT FOR AN OMNIDIRECTIONAL DYNAMIC STRESS GAGE

Abstract

An analysis of the transient response of the pressure in an embedded elastic inclusion due to an incident compressional wave. Also included in the study is an outline of a design for an omnidirectional pressure transducer with a response capable of being analyzed by the methods of the theory of elastic wave propagation and diffraction. The transducer proposed is an elastic spherical inclusion that is to be buried in the ground and is sensitive, through strain gages, to the mean stress or pressure at its origin. Both frequency response and transient behavior are treated.
