承受统一外压的各向异性复合材料长圆筒的概率研究

his study focuses on the load and resistance factor design procedure for anisotropic long composite cylinders under external pressure. A sensitivity analysis is performed to research the influences of statistical characteristics of variables on partial safety factors and thickness of cylindrical wall by applying advanced first-order second-moment method. The results show inside radius and model uncertainty significantly affect the design results, whereas longitudinal modulus, transversal modulus and external pressure have little effects, and shear modulus and Poisson's ratio almost have no effects. A series of tests were performed, which showed a good agreement between the experimental and analytical results..
