- A SOC one-dimensional calculation of an underground nuclear test is presented to exemplify the shock propagation and spall phenomenology commonly predicted. Then to examine the effects of spherical divergence on spall, a series of SOC calculations, at different radii of curvature, are conducted and prediction of depth and velocity for the first spall zone are compared with predictions from simple analytic theory. The excellent agreement in this comparison verifies that the SOC code accurately represents the physics of spalling. This study also indicates that the total spall depth is independent of divergence because of the compensating effect that subsequent convergence has on the reflected wave. The latter result implies that the total depth of spall calculated for each underground nuclear tests must be critically examined and evaluated. Finally, SOC calculations for nuclear detonations in tuff and granite are performed to demonstrate the significant effect that variations in material response under shock loading have on shock propagation and spall.
