Abstract: With the help of finite element method, the mechanical parameters in the performance of mul?ti-layered tube were analysed. Stress and strength analysis, as well as the dynamic characteristics were studied. The results reveal that higher ratios of strength and rigidity are achieved in a multi-layered tube. A theoretical basis is provided for engineering applications of multi-layered tubes.

Key words: composite material , composite multi-layered tube , mechanical analysis , finite element method
