摘要拉胀蜂窝材料由于其良好的力学特性以及稳定的吸能特性，广泛地应用于各类防护结构。本文针对星型拉胀在压剪复合加载下的力学特性开展了研究工作。首先，基于有限元技术建立星型拉胀蜂窝材料的数值模型，并基于增材制造技术和万能试验机开展验证试验，并且开展了星型拉胀蜂窝材料在不同压剪复合加载角度和速度下的仿真研究，对星型拉胀蜂窝材料在各个加载工况下的力学特性与变形模式开展研究，结果表明星型拉胀蜂窝材料在准静态复合加载下依托胞元旋转发生整体变形，并产生倾斜变形带压溃，随着加载速度提升，由于惯性效应的增强，细观结构间的挤压变形更加充分，材料变形模式由整体变形向局部变形转变，形成冲击波。进而，基于椭圆方程对星型拉胀蜂窝材料初始屈服应力进行拟合，建立星型拉胀蜂窝材料的准静态/动态屈服面，随着速度的提高，屈服面呈现出明显强化；最后通过对星型拉胀蜂窝材料的吸能特性研究表明，随着加载角度的增大，材料法向和切向总吸能分别呈现出下降和提高的趋势，且切向吸能特性对角度的改变相对法向方向更加敏感。

Abstract：Auxetic honeycomb materials are widely used in various protective structures due to their good mechanical properties and stable energy absorption properties. In this paper, the finite element technology is used to establish the numerical model of the star auxetic honeycomb material, and the verification experiment is carried out based on the additive manufacturing technology and the universal testing machine. Furthermore, the simulation investigation of star-shaped auxetic honeycomb material under different compression-shear composite loading angles and speeds was carried out, and the yield surface of star-shaped auxetic honeycomb material was established. The results show that the star-shaped auxetic honeycomb material undergoes overall deformation under low-speed composite loading relying on the rotation of the cells, and produces oblique deformation belt crushing. More fully, the material deformation mode changes from overall deformation to local deformation, forming stress waves. The initial yield stress of the material was fitted by the ellipse equation, and the yield surface of the star-shaped auxetic honeycomb material was established. With the increase of the speed, the initial yield surface of the material showed obvious strengthening. The total energy absorption in the tangential and tangential directions showed a decreasing and increasing trend, respectively, and the tangential energy absorption characteristics were more sensitive to the change of the angle than the normal direction.

Key words： auxetic material star honeycomb complex loading yield surface energy absorption
