在这项研究中，对称和反对称[θ/−θ] sshell设计的最大爆破压力的最佳角铺层方向进行了检查。研究了纤维缠绕复合材料压力容器在交变纯内压作用下的爆破压力。研究了温度和缠绕角度对纤维缠绕复合材料压力容器的影响。采用有限元法和实验方法对最佳缠绕角进行了验证。为了预测压力容器的爆破破坏压力，提出了一种基于Lekhnitskii理论的弹性求解方法。采用蔡武准则、最大应变和应力理论对钢管的爆破失效压力进行了验证。给出了不同方位角下的解并进行了讨论。玻璃钢（GRP）管制造的E-玻璃-环氧树脂和测试的封闭端条件。测试样品具有四层，其具有各种取向角。这些层对于[45°/−45°]s、[55°/−55°]s、[60°/−60°]s、[75°/−75°]和[88°/−88°] s取向是对称和反对称取向的。在这项研究中，PLC控制的液压试验机已被利用。在E-玻璃-环氧复合材料平板层上测量了湿热和其他机械性能。利用商用软件ANSYS10.0，将一些解析解和实验解与有限元解进行了比较，在某些方向上，得到了接近的结果。
In this study, optimal angle-ply orientations of symmetric and antisymmetric [θ/−θ]sshells designed for maximum burst pressure were examined. Burst pressure of filament wound composite pressure vessels under alternating pure internal pressure was investigated. The study deals with the influences of temperature and winding angle on filament wound composite pressure vessels. Finite element method and experimental approaches were employed to verify the optimum winding angles. An elastic solution procedure based on Lekhnitskii’s theory was developed in order to predict the burst failure pressure of the pressure vessels. The Tsai-Wu failure criterion, maximum strain and stress theories were applied for verifying the burst failure pressure of tubes. The solution was presented and discussed for various orientation angles. Glass reinforced plastic (GRP) pipes were manufactured by E-glass–epoxy and tested for the closed-ended condition. Test specimens had four layers, which had various orientation angles. The layers were oriented symmetrically and antisymmetrically for, [45°/−45°]s, [55°/−55°]s, [60°/−60°]s, [75°/−75°]sand [88°/−88°]sorientations. For this study, a PLC controlled hydraulic pressure testing machine has been utilized. The hygrothermal and other mechanical properties were measured on E-glass–epoxy composite flat layers. Some analytical and experimental solutions were compared with the finite element solutions, in which commercial software ANSYS 10.0 was utilized; close results were obtained between analytical and experimental solutions for some orientations.
