摘要

摘要: 在调研现有文献复合材料结构三维数值分析中材料参数的基础上,阐述了基于单层板材料性能数据建立复合材料三维材料参数的方法.通过对复合材料π接头结构的三维数值模拟和试验,研究了三维材料参数中不确定参数对结构刚度预测的影响;分别采用三维修正的最大应力准则、最大应变准则、蔡-胡准则和Hashin准则评价π接头的初始破坏,结合试验数据,研究不同失效准则对复合材料π接头结构的适用范围以及材料参数对初始破坏强度预测的影响.研究工作可为一般层合复合材料结构的三维建模提供参考,并为深入理解复合材料π接头结构力学性能、准确预测其破坏强度提供理论支持.

Abstract: The method to determine 3D composite material properties by means of engineering constants of composite lamina was summarized by investigating lots of existed literatures. The effect of uncertain variables in material parameters upon the stiffness prediction was researched by 3D numerical simulation and the corresponding experiments of composite π joint structure. Further, the initial failure of composite π joint structure was assessed by the modified maximum stress and strain, Tsai-Hu and Hashin failure criteria. The damage onset loads with different failure criteria and material parameter model were compared and the influence of material parameter model on the prediction of initial failure load and location was expatiated together with the experimental data. The research provides reference for numerical analysis of general 3D composite laminate structures. Moreover, it offers theoretical support for understanding mechanics behaviors and accurate strength prediction of composite π joint.
