纤维增强层板的杂交模型及其应用

HYBRID MODEL OF COMPOSITE LAMINATS AND ITS APPLICATIONS

摘要: 根据修正余能原理导出的杂交应力模型,可用于纤维增强叠层各向异性板的分析.这类板的横向剪切变形效应必须予以考虑,因而层板不同层的表面法线的转角是不同的.算例表明本文导出的杂交应力模型具有较高的数值精度.

Abstract: The hybrid stress model for fiber reinforced copposite laminates is derived by the principle of modified complementary energy.The effect of transverse shear deformation is considered and angle of rotation of surface normal for each layer is different.
