Review on dynamic tensile strength of concrete measured using split Hopkinson pressure bar technique

  • Online:2016-08-25 Published:2016-08-25

Abstract: In this paper, studies on the dynamic tensile mechanical properties of concrete measured using the split Hopkinson pressure bar are summed up and analyzed, and measurement methods of concrete tensile strength based on such a pressure bar are discussed in detail. We also discuss the influence of various factors on the dynamic increase factor (DIF) of concrete-like materials, such as experimental methods, shape and size of specimens, aggregate size, saturation degree, materials of specimens. This review concludes that the value of DIF increases with the decrease in the size of specimens in spalling tests, or in the aggregate size in direct tensile tests. Different types of concrete could differ in their values of DIF. The problems needed to be solved in further studies are suggested in this paper.
