In order to investigate the dynamic tensile strength of rock after high temperature under impact loading

the dynamic flattened Brazilian disc experiments of marble after different temperatures subjected to radial impact compression are carried out by using split Hopkinson pressure bar (SHPB). The temperature and impact loading rate effects on the dynamic tensile strength and dynamic tensile failure form of marble under impact loading after high temperatures are analyzed. It is demonstrated that after different high temperatures the dynamic tensile strength of marble is substantially higher than the static tensile strength and has an obvious impact loading rate strengthening effect. As temperature increases

the dynamic tensile strength of marble under the same impact loading rate increases first and then decreases. Meanwhile

the temperature and impact loading rate both have strong influence on the dynamic tensile failure form of marble under impact loading after high temperature.
