RESEARCH ON DYNAMIC CRUSHING OF LAYERED YIELDING STRESS-GRADIENT CIRCULAR HONEYCOMBS
-
摘要: 基于功能梯度材料的概念,建立了具有固定相对密度的分层屈服强度梯度圆形蜂窝材料模型。在此基础上具体讨论了屈服强度梯度和冲击速度对圆形蜂窝材料变形模式及能量吸收性能的影响。研究结果表明,屈服强度梯度的变化使得蜂窝材料的局部变形模式发生了变化。中低速冲击下,分层梯度蜂窝材料冲击端的动力响应表现出分段平台特性。合理地调节屈服强度梯度的变化可以减小初始峰值应力,并能够有效地控制进入被保护结构的应力值,同时实现蜂窝材料单位质量能量吸收率的控制。研究结果可为功能梯度蜂窝材料的研究和设计提供 参考。Abstract: Based on the concept of functionally gradient materials,a model of a layered yielding stress gradient circular honeycomb is developed. The effects of yielding stress gradient and impact velocity on the deformation modes and energy absorption capacities of circular honeycombs are discussed. The research results show that the deformation modes of circular honeycombs change with different yielding stress gradients. The dynamic response curves of layered yielding stress-gradient circular honeycombs show piecewise platforms under moderate and low compact velocities. Through the proper adjustment of the yielding stress gradient,the initial stress peak can be reduced, the values of the stresses transmitted into the structures can be greatly reduced,and the energy absorption can be controlled effectively. These results can provide valuable suggestions in the study and design of the functionally gradient honeycombs.
