Junior Jade events: An investigation of decoupling phenomenology
With five 8-pound high-explosive events, we have explored aspects of the containment phenomenology of partially decoupled events. Three events drove multiple fractures and showed little cavity growth, suggesting that the fracture propagation was part of the dynamic process. Two events were contained; their cavity volumes grew by factors of approximately two and three with the tighter-coupled event showing the larger growth. With the five events we see a spectrum of results ranging from hydrofrac type fracture propagation through multiple fracture propagation to the fully contained case. For the multiple fracture case a partial residual stress field may control the release of the cavity pressure. Measurements of cavity pressure versus time provides a valuable diagnostic of containment. 2 refs., 7 figs., 1 tab.
