Simulating the behavior of concrete under tensile high rate loading

Abstract

Although the compression bar (Split Hopkinson Pressure Bar, SHPB) has been widely used to determine the dynamics properties of a material, but dynamic tensile testing equipment has not been standardized because of equipment size, sample size as well as loading speed all affect the test results. This paper will study one of the dynamics tensile devices is SHTB (Split Hopkinson Tension Bar). The research method is a simulation with Abaqus software. Stability and results of the simulation are presented through influencing parameters such as loading speed, specimen size.
