Spherically Symmetric Numerical Simulation of the SRI Grout Spheres Containment Experiments.
Abstract
As part of the DNA stemming and containment program for underground nuclear testing, Stanford Research Institute is conducting laboratory investigations to develop a containment experiment for studying residual stress fields around an explosively generated cavity in a grout sphere. Here we present the S3 numerical simulations of the spherically symmetric aspects of these laboratory investigations. Calculations are presented which simulate the high explosive detonation and the subsequent dynamic processes which result in the formation of the compressive residual stress fields around the cavity. Results are presented showing our ability to simulate the detonation of the explosive charges in water and in grout. Preliminary results are shown for a calculational model which simulates the spherically symmetric venting and subsequent hydrofracture of the cavity.
