JUNIOR JADE - containment phenomenology of decoupled events
With five 8 pound high-explosive experiments, the author has investigated aspects of the containment phenomenology of partially decoupled events. In three experiments he observed multiple fractures and little cavity growth. In the final two experiments there were no fractures and cavity volumes grew by factors of approximately two and three. With the five experiments a spectrum of results ranging from hydraulic fracture - like crack propagation through multiple fracture propagation to the no fracture, or fully contained, case, was observed. For the multiple fracture experiments a partial residual stress field may have controlled the release of the cavity pressure. Measurements of cavity pressure versus time provided containment diagnostics; post event mining allowed visual observation of the cavities and fractures.
