Buckling Analysis of the Composite Warhead Under External Pressure and Axial Force

In this study, the analysis, manufacturing and experimental buckling test of a composite warhead subjected to external pressure and axial load are investigated. Variation of angle and thickness along the none length are obtained, also the optimum filament winding design is achieved by considering minimum disordered patterns and wasting materials. In continue the static and buckling analysis of the composite warhead is performed using FEM software with Eigen value Analysis. The variation of the wound angle and the thickness are surveyed and the optimum angle is extracted. The composite warhead is manufactured based on the optimum angle. The process and equipments of the external pressure test are designed and the composite warhead is tested. The obtained buckling results of the FEM and the experimental are compared and also the efficiency of this method in prediction of buckling behavior of the composite warhead is demonstrated.
