摘要

摘要: 基于有限元方法,研究了复合材料蜂窝夹芯板斜接式挖补修理的稳定性问题。利用商用有限元分析软件MSC.Patran/Nastran和蜂窝夹芯等效方法,建立了蜂窝夹芯板斜接式挖补修理结构稳定性三维有限元分析模型。并通过大量的数值算例,拟合得到了不同挖补角度以及胶层厚度对蜂窝夹芯板斜接式挖补修理结构屈曲特征值的影响规律。

Abstract: Based on the finite element method,the stability problem was studied for the composite honeycomb plate with a scarf repair.Using commercial finite element analysis software MSC.Patran/Nastran and the equivalent method of honeycomb core,a three-dimensional finite element model is established for the composite honeycomb plate with a scarf repair.Furthermore,the influence of the scarf angles and adhesive thickness on the buckling eigenvalues is calculated through the numerical examples and fitting method.
