An Experimental Study of S Wave Generation by Fracture Damage in Underground Nuclear Explosions
Abstract
High-speed digital photography was used to observe the generation of S waves by explosions in fracture-damaged photoelastic Homalite plates. We found that either a preferred orientation of the pre-existing fractures or an anisotropic initial stress field produced significant S wave radiation in the far field. These experimental observations support theoretical predictions by Johnson and Sammis (2001).
