Finite-element strength and stability analysis and experimental studies of a submrine-launched missile's composite dome

摘要

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 accoring 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 exteranl pressure. Experiments are compledted for studying the strength of the dome under axial compression and itnernal pressure and the stability of the dome under the combination of axial compression and external pressure.
