论述了Ｊｏｎｅｓ－Ｎｅｌｓｏｎ－Ｍｏｒｇａｎ模型的构成原理及其参数的确定方法，利用这个模型研究了纤维缠绕复合材料的非线性本构关系。推导和建立了纤维缠绕壳体大变形有限元公式和有限元模型。在同时考虑材料非线性和大变形情况下对纤维缠绕壳体内压进行了有限元分析计算，获得了与实验结果符合较好的理论预报结果。
The principle of the Jones-Nelson-Morgan model and the determination of its parameters are discussed. The nonlinear constitutive relationship of the fiber-wound composites is studied by using this model. The finite element formula and finite element model of large deformation of fiber wound shell are deduced and established. The internal pressure of the fiber wound shell was calculated by finite element analysis while considering the material nonlinearity and large deformation, and the theoretical prediction results in good agreement with the experimental results were obtained.
