Static and Dynamic Behavior of Granite in Split Tension

Abstract:

Tensile strength is one of the most important mechanical properties of granite. It is a key parameter for strength design, safety analysis of granite structures. In the present paper, experimental investigation on static and dynamic splitting tensile behavior of granite is carried out with Brazilian disc (BD) test. The incident wave of SHPB for the dynamic BD test was designed with pulse shaper. The results show that the dynamic tensile strength of granite is heightened with increasing strain rate.
