Stress Wave Propagation in Rock

  • D. E. Grady

Abstract

There are a number of pressing engineering and geophysical problems involving transient finite deformation of rock and rock masses. An interesting and representative example is a borehole drilled into a geological formation which is packed with explosives and detonated in an attempt to rubblize the adjacent medium for the purpose of in situ resource recovery. The explosive energy is coupled into the rock near the borehole perimeter and the initial compressive stresses can be on the order of 5 GPa. The disturbance is propagated away from the borehold as a large-amplitude deformation wave which attenuates with radial distance, eventually reaching a level for which material response is purely elastic. Wave propagation and attenuation to this level is complex and depends on the dynamic material response of the zone affected. Such response can involve compressive shear yielding, phase transitions, and tensile fracture. Strain rates typically range between about 105/s during early time response to about 101/s during late time response.
