| 摘 要： | 采用变截面大尺寸的Hopkinson压杆对素混凝土与聚丙烯纤维混凝土试件进行了冲击压缩(split-hopkinsonbe,SHPB)试验,得到了不同应变率下的聚丙烯纤维混凝土动态压缩强度及应力-应变全过程曲线,证实了聚丙烯纤维混凝土材料的应变速率敏感性,结果对于计算聚丙烯纤维混凝土在高速冲击及爆炸条件下的响应很有意义.

| Abstract: | By using the large-size Hopkinson pressure bar with variable cross-sections,split-hopkinson bar tests have been made on cement concrete and polypropylene fiber concrete specimens.The dynamic compression intention of concrete under variable strain rate,and the overall-process curves of the stress-strain obtained from the tests prove the strain rate sensitivity of concrete material,which is important in calculating the receptance of polypropylene fiber concrete in high-speed impact and blasts. |
