【Abstract】

<正>Tensile strength is an important material parameter for rocks.Similar to the static tensile strength study,there are various methods proposed to measure the dynamic tensile strength of rocks. Here we examine dynamic tensile strength values measured from three methods:dynamic direct tension,dynamic Brazil test,and dynamic semi-circular bend.We found that the dynamic tensile strength from direct tension has the lowest value,and the dynamic
