Buckling Analysis of Fiber Crossover Composite Cylindrical Shells
This study considers the situation of fiber crossover and establishes a finite element analysis model for the buckling of fiber-wound cylindrical shells.The effectiveness of the model and computational methods is verified through numerical examples.Using this model,the study investigates the variation of buckling loads of cylindrical shells with parameters such as winding angle,thickness-to-diameter ratio,and length-to-diameter ratio,and analyzes the influence of fiber crossover on the buckling performance of the shells.The computational results show that the buckling critical load and mode of fiber-wound composite material cylindrical shells are significantly related to the winding angle,length-to-diameter ratio,and number of windings.Under specific conditions,such as when the winding angle is in the range of[10°-30°],the length-to-diameter ratio is relatively small,or the number of windings increases,fiber crossover has a noticeable impact on the buckling critical load.
