Finite Element Analysis of Composite Overwrapped Pressure Vessel Based on the Laminated Plate Theory

Article Preview

Abstract:

The composite overwrapped pressure vessel shell was analyzed by using the laminated plate theory. The conventional 2D laminated plate was transformed into a 3D curved plate by setting a reasonable material direction and thickness, and the finite model of the pressure vessel was built. The sress-strain field of the pressure vessel was obtained. Analysis results show that cylindrical section and head section has high stress concentration, and it is the weakest part.
