Studies Pertaining to Solid Propellant Fracture.
Abstract
The study of propellant fracture has been subdivided into three parts: a fracture criterion is developed for stress fields producing mixed mode crack propagation by drawing a comparison with fracture in uncracked geometries; a means for predicting crack growth and velocity has been developed for linear viscoelastic materials strictly on the basis of stress intensity factors. A fracture characterization of critical stress intensity factor for a CTPB propellant has been completed, which facilitates the application of the theory; and, extensive dewetting experiments have been completed which have confirmed prior theoretical developments of a quasielastic dewetting theory.
