Study on Interface Failure of Propellant and Liner Material with Mechanics Analysis

Article Preview

Abstract:

In order to analyze failure phenomena and mechanical properties of propellant-liner interface material, both experimental study and modeling were carried out. The adhesive system was observed under tensile. Based on experiment, the finite element analysis was implemented. Results show that the failure is initiated on a certain point near the propellant and the deformation concentration of localization zone and the macro-cracks occur. The failure process can be modeled and stress distributions can be obtained by introducing cohesive element. The method offers references to interface designing
