Numerical Analysis of Multiscale Progressive Damage for Solid Rocket Motor Composite Shell

Article Preview

Abstract:

In this study, the evolution of laminates in four damages are analyzed based on the established multiscale reinforced composite material damage model from a single cell model, single plate model to multilayer fiber model of carbon fiber. The validity of the model is verified by numerical simulation of laminate tensile test. Based on the established model to calculate the [±26/902]3 damage evolution of SRM due to withstand pressure in the straight section and the results show that: the calculation is consistent with the experimental results of displacement, and the role of a variety of common damages result in reduced performance of the housing.
