SOLID PROPELLANT STRUCTURAL INTEGRITY INVESTIGATIONS. DYNAMIC RESPONSE AND FAILURE MECHANISMS.
Abstract
This document presents the results and conclusions of a theoretical and experimental research program to correlate mechanical response and failure in solid propellants with basic material structural characteristics. The program was concentrated on the study of propellant dynamic physical properties and structural failure phenomena. Major emphasis in the program, directed at the complementary problems of propellant viscoelastic properties and failure mechanisms together with examination of the effects of propellant binder and filler physical characteristics on these general aspects of its behavior, is reported upon. Measurements of viscoelastic properties of various propellants using transient techniques are demostrated and results are presented. Investigation of propellant viscoelastic properties in dynamic shear is also discussed. Failure criteria studies are presented in which propellants were tested to failure in one and two-dimensional stress states, as are systematic relationships between physicochemical formulation variations and propellant failure characteristics. Conclusions are given on the isolation of a maximum tensile stress failure criterion. (Author)
