Abstract
The paper presents a finite element model for strength analysis of a submarine-launched missile's composite dome under axial tension and internal pressure. Characteristics of stress distribution and locations and loads of failure are determined according to the model. Another finite element model is developed to calculate stability of the dome under axial compression, external pressure and the combination of axial compression and external pressure. Experiments are completed for studying the strength of the dome under axial compression and internal pressure and the stability of the dome under the combination of axial compression and external pressure.
