| 摘 要： | 利用Hopkinson压杆,以试验数据为依据,研究了4种不同密度的泡沫混凝土材料在冲击载荷下的动态力学压缩性能.通过相同加载速率下对泡沫混凝土的动态力学性能比较,得到了高应变率下的泡沫混凝土随着孔隙率降低其最大破坏应力与弹性模量均增大这一变化规律.同时对泡沫混凝土抗冲击和吸能机理进行了探讨.

| Abstract: | Based on the experimental data, Hopkinson pressure bar （SHPB） was used to study the dynamiccompression properties of four kinds of foam concrete with shock load. After comparing dynamic propertiesof foam concrete at the same loading rate, the results show that, at high strain rate, both maximum deconstruction stress and dynamic elastic modulus increase gradually with the decrease of porosity of concrete.The anti-impact properties and endergonic mechanism of foam concrete were discussed. |
