To investigate the strengthening and toughening effect of fiber on seawater coral aggregate concrete (SCAC) under an impact load, the dynamic mechanical response of SCAC with mono PVA fiber or hybrid PVA-steel fiber at different strain rates was tested by using a ϕ75 mm Split Hopkinson Pressure Bar. The impact properties and failure characteristics were simulated using a software named ANSYS/LS-DYNA. The results indicate that the addition of fibers may improve the embrittlement degree and dynamic mechanical properties of SCAC. The enhancement effect of hybrid fiber on the strain rate sensitivity and dynamic increase factor of SCAC is better than that of mono PVA fiber. The damage degree of SCAC gradually decreases with the increase of PVA fiber content, while the integrity of the hybrid fiber SCAC is better at each strain rate. The number of final deleted elements in the simulated sample is significantly reduced after adding fibers, and the simulated results show the dynamic mechanical properties and failure degree of SCAC with various fiber contents.

为探究冲击荷载下纤维对海水珊瑚骨料混凝土(SCAC)的增强增韧效果,采用ϕ75 mm分离式Hopkinson压杆测试了单掺聚乙烯醇(PVA)纤维或混杂PVA-钢纤维SCAC在不同应变率下的动态力学响应,利用ANSYS/LS-DYNA模拟其冲击性能及破坏形态特征。结果表明,掺加纤维可改善SCAC的脆化程度和动态力学性能;混杂纤维对SCAC应变率敏感性和动态强度增长因子的提升效果优于单掺PVA纤维;SCAC的破坏程度随PVA纤维掺量增加逐步改善,而混杂纤维SCAC在各应变率下的完整性则更好;模拟所得试块失效单元数在掺入纤维后显著减少,模拟结果反映出各纤维掺量SCAC的动态力学行为与破坏程度。

为探究冲击荷载下纤维对海水珊瑚骨料混凝土(SCAC)的增强增韧效果,采用ϕ75 mm分离式Hopkinson压杆测试了单掺聚乙烯醇(PVA)纤维或混杂PVA-钢纤维SCAC在不同应变率下的动态力学响应,利用ANSYS/LS-DYNA模拟其冲击性能及破坏形态特征。结果表明,掺加纤维可改善SCAC的脆化程度和动态力学性能;混杂纤维对SCAC应变率敏感性和动态强度增长因子的提升效果优于单掺PVA纤维;SCAC的破坏程度随PVA纤维掺量增加逐步改善,而混杂纤维SCAC在各应变率下的完整性则更好;模拟所得试块失效单元数在掺入纤维后显著减少,模拟结果反映出各纤维掺量SCAC的动态力学行为与破坏程度。

To investigate the strengthening and toughening effect of fiber on seawater coral aggregate concrete (SCAC) under an impact load, the dynamic mechanical response of SCAC with mono PVA fiber or hybrid PVA-steel fiber at different strain rates was tested by using a ϕ75 mm Split Hopkinson Pressure Bar. The impact properties and failure characteristics were simulated using a software named ANSYS/LS-DYNA. The results indicate that the addition of fibers may improve the embrittlement degree and dynamic mechanical properties of SCAC. The enhancement effect of hybrid fiber on the strain rate sensitivity and dynamic increase factor of SCAC is better than that of mono PVA fiber. The damage degree of SCAC gradually decreases with the increase of PVA fiber content, while the integrity of the hybrid fiber SCAC is better at each strain rate. The number of final deleted elements in the simulated sample is significantly reduced after adding fibers, and the simulated results show the dynamic mechanical properties and failure degree of SCAC with various fiber contents.
