摘要 为了研究共面准静态压缩载荷作用下凹六边形蜂窝芯材的力学行为,设计了相关有限元分析模型.基于该模型,进行了大量有限元模拟计算.将计算得到的变形模式、响应曲线和峰应力值分别以图、力位移曲线和数据表的形式列出.壁厚边长比和扩展角对准静态峰应力的影响进行了详细讨论,基于有限元计算结果给出了准静态峰应力与结构参数之间的经验关系式. To present the mechanical behaviors of cissoidal hexagonal cores under the in‐plane quasi‐static compression loadings ,a finite element model is introduced .Based on this model many finite element simulations were carried out .The calculated deformation processes ,re‐sponse curves and values of plateau stress are presented in the forms of diagrams ,force‐dis‐placement curves or data tables ,respectively .The influences of ratio of cell wall thickness to edge length and expanding angle on the quasi‐static plateau stress are discussed in detail .The empirical expressions of quasi‐static plateau stress in terms of configuration parameters are given based on the FE simulation results .
