提出纱态概念 ,解决了任意结构三维机织预制件的结构表征问题 ,提出了交叉等效曲面板模型 ,借助三次多项式插值原理 ,建立了反映三维机织复合材料本构关系的计算机模拟模型 ,并以试验进行了验证。
The concept of yarn state is proposed to solve the problem of structural characterization of three-dimensional woven preforms with arbitrary structure. A cross-equivalent curved panel model is proposed. By means of cubic polynomial interpolation principle, a computer simulation model reflecting the constitutive relationship of three- And tested by the test.
