| 摘要: |
| 在蜂窝纸压溃的相关理论分析的基础上，在有限元软件MARC中创建了4个代表性的模型；以屈曲理论和准静态分析为基础，完成了轴向载荷的非线性压溃过程分析。在有限元分析时，将该过程分为4个过程，即线弹性、弹塑性、塑性坍塌和密实化过程。结果表明：在纸芯数量较少的情况下，随着纸芯数量的增加，等效应力和剪应力不断提高。压溃过程通过实验得到了初步验证。 |

| Abstract: |
| Four typical models were established in the finite element software MARC based on theoretical analysis of honeycomb paperboard crush. The analysis of nonlinear crush process subjected to axial load was carried out based on yielding theory and quasi-static analysis. The process was divided into four steps, linear elastic, elastically plastic, plastically collapsing, and densifying. The result showed that the equivalent stress in the models and shear stress constantly increases in response to the increase of core-paper quantity under the condition of less core-paper quantity. The crush process was verified by experiment. |
