Non-Linear Fracture Mechanics: New Theories of Solid Propellant Response and Fracture Behaviors

Abstract

Non-linear fracture mechanics is a newly developing analytical method for the treatment of fracture behaviors in composite solid propellants. The work presented here was designed to show the need for these concepts and the material behaviors that must be taken into account by the theory. An empirically derived relation forms the fundamental point of departure for the non-linear fracture criterion. In addition, a non-linear strain energy function was investigated as the initial effort in developing the required analytical relations.
