摘要/Abstract

摘要： 制备了帽型、泡型、工字型三种夹芯结构复合材料,研究三种夹芯结构在弯曲载荷下的响应行为,并利用有限元的方法研究夹芯结构在弯曲载荷下Von-Mises应力分布,利用Tsai-Hill屈服准则判定有限元模型的屈服情况,观察发生屈服的区域。结果表明,帽型夹芯结构具有最大的弯曲刚度与抗弯强度。三种夹芯结构发生破坏的区域不同,帽型夹芯结构破坏主要出现在压头区域、上面板的压头边缘区域、芯子压头正下方的拐角处;泡型夹芯结构破坏出现在芯子支撑区域;工字型夹芯结构破坏出现在下面板支撑区域。

Abstract: In this paper, three types of composite sandwich panels, hat, bubble, and Ⅰ were fabricated, and the bending performance of composite sandwich panels were studied. Finite element analysis (FEM) method was used to investigate the stress distribution on composite sandwich panels suffering from bending load, and Tsai-Hill failure criteria was used to predict the failure mechanism of the composite structures. Results show that the bending stiffness and maximum load of hat sandwich panel is the highest among the three sandwich structures. The damage zone of three kinds of sandwich are different. The damage zone of hat sandwich structure occurred at the edge of indenter and core corner below the loading zone. The damage zone of bubble sandwich occurred in the support region of core. The damage zone of Ⅰsandwich is located at the support region of bottom plate.

Key words: composite sandwich panels, three-point bending test, finite element analysis, bending stiffness, damage zone
