%X The occurrence of fibre crossover and undulation(FCU) is inherent of the filament windingproc ess. However, the study on the effect of FCU on the mechanical performance and failure of filament wound composite(FWC) structure were mainly experimental research. So in this paper, a macro-meso failure analysis model for FWC considering FCU is established based on Puck, Hashin failure criterion and Linde stiffness degradation model. The influence of fibre crossove r and undulation on the stiffness failure is calculated and analyzed. The numerical results show that the strain in FCU region is higher by about 1.07¨C1.13 times than it in laminate region, the FCU have a certain influence on the failure strength of filament wound composite and the failure position of FWC under axial tensile load and internal pressure is mainly located FCU region and the failure position under axial compressive load is related to the winding angle
