MECHANICAL STUDY ON Y-TYPE COMPOSITE MATERIAL-STEEL JOINT OF SHIP

Abstract

Abstract: In this paper, the Y-type composite-steel plate joint of warship was studied. The finite element method was used to calculate the Y-type composite joint. The three-dimensional Hashin failure criterion was used for fiber failure, the maximum stress criterion was used for sandwich layer. And the UMAT failure subroutine is compiled to analyze material failure. The reinforced joint and the unreinforced joint were analyzed, and finally verified by experimental method. The results show that the reinforcement can significantly increase the load of Y-type embedded steel plate joints, and change the failure mode of joints from skin damage to delamination damage of adhesive layer and PVC shear failure at the embedded steel plate. With the increase of the distance between steel plate and PVC, the mechanical properties of joints decreases. When the force decreases, the damage will occur ahead of time.

Key words: Y-joint, embedded steel plate, composite material, finite element simulation, progressive damage
