        Numerical study of progressive damage analysis on filament wound composite tubes embedded with metal joints

        Song Lin,Linan Xu,Shuangwen Li,Xuran Liu,Weili Jiang,Xiaolong Jia 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.11

        This paper investigates the progressive damage of filament wound composite tubes embedded within metal joints. Finite element analysis (FEA) modellings were provided through CADWIND filament wound simulation software, and progressive damage analysis of composite tubes was carried out using the Puck criterion under tensile loading. Besides, the ultimate tensile loading of composite tube was carried out. It was found that the inside metal joint extruded the outer composite layers, which resulted in further failure damage of the composite tubes. Furthermore, thickening the composite layer outside metal joint was beneficial to improve the tensile load of the composite tube. Moreover, the numerical results of the FEA provided a reasonably good agreement with the experimental results, which was less than 10 % on the ultimate tensile loading value. Finally, the FEA with the Puck criterion was suitable to predict the progressive damage of filament wound composite tube embedded with metal joints.
