Three-Dimensional Crack Analysis in Solid Propellant by an Hybrid Stress Finite Element Method,

Abstract

Numerical analysis methods for cracks in solid propellant grains should include the proper stress singularity and account for material incompressibility. An hybrid stress finite element method for the three-dimensional analysis of straight crack fronts has been developed. A modification to extend the method to curved crack fronts is proposed.
