Abstract:
This report includes the Phase I preliminary study in which the Quinlan theory was critiqued, alternate approaches were studied and detailed research planning accomplished. Also included are detailed experimental evaluations of propellant during Phases 2 and 3, the uniaxialisothermal investigation and the two-dimensional variable temperature investigation. The report also covers the validation of the accuracy of the constitutive theory in a three-dimensional state of stress and strain. Detailed subcontractor theoretical development and predictions are given.
