| 摘 要： | 对毛竹(Phyllostachys edulis)、麻竹(Dendrocalamus latiflorus)和绿竹(Dendrocalamopsis oldhami)及箣竹(Bambusa arundinacea)等4种竹材进行了顺纹(轴向)和横纹(径向)抗压动态破坏过程试验,分析了竹材的纵、横向抗压力学性能,并对不同品种不同年龄的竹种抗压强度进行了比较.结果表明:竹材的抗压本构关系、动态破坏过程以及试样的宏观断口形貌间表现出很好的相关性,并且竹材的品种、年龄和抗压方向对竹材的抗压强度都有影响. |

| Abstract: | Phyllostachys edulis,Dendrocalamus latiflorus,Dendrocalamopsis oldhami,Bambusa arundinacea were selected.The dynamic damage process parallel and perpendicular(radial direction)to the axial direction was tested.After the testing,the bulk microstructure and compressive mechanical properties of bamboo were studied.The results show that the strain-stress curve,dynamic damage process and damage cross surface are highly related,and the bamboo species,age and the compressive direction are related to the compressive strength.The bamboo compressive dynamic damage process is critical to understand the bamboo mechanical properties. |
| Keywords: | Bamboo Compressive strength Dynamic damage process |
