“…Wu et al investigated the dynamic tensile failure of rock under static pre-tension, and found that rock dynamic tensile strength decreased with increasing the pre-tension, while the total tensile strength of the rock was roughly independent of the pre-tension [12]. Gomez et al used the SHPB to explore the dynamic tensile property of granite with a pre-existing damage [13]. These previous works have indicated that the dynamic tensile strength of rock is influenced by many factors.…”

In order to investigate the dynamic behavior of medium-fine-grained Huashan granite treated by different temperatures, the splitting tests on the granite specimens are carried out using an improved split Hopkinson pressure bar (SHPB). The dynamic force equilibrium condition in the specimen is basically satisfied. The results show that with increasing treatment temperature, the ultrasonic P-wave velocity decreases, while thermal damage accordingly increases. The damage evolution follows the logistic curve model. For a temperature at or below 500°C, all the specimens break diametrically into two halves at relatively low impact velocities. As the impact velocity rises, the triangular crushed zones are observed at the two loading ends of the specimen. When the temperature exceeds 500°C, the damage of the specimen becomes severe, and even completely pulverized under high impact velocity. There are good correlations between the splitting strength and the treatment temperature, the ultrasonic P-wave velocity as well as the thermal damage. In addition, the splitting strength is slightly abnormal at 100°C, namely the strength becomes lower than that at room temperature with increasing impact velocity. Overall, the decay of the splitting strength with thermal damage for the treatment temperatures over 100°C accords with the power function. Moreover, the splitting strength of specimen is sensitive to strain rate at high temperature, but the increasing rates are different under different ranges of temperature.

“…Another difficulty in uniaxial tensile tests is that the test specimen is under the influence of moment effects during the tensile test due to eccentricity. Gomez [12] and Mier [13] reported that an increase in load eccentricity may decrease the tensile stress. Swaddiwudhipong et al [14] studied the strain capacity in direct tension and the tensile strength of concrete produced with different types of cement at early ages in their tests.…”

“…The use of concrete structural elements can be easily found in buildings, highways/bridges, runways, jetties, etc. Many experimental and theoretical studies have been carried out to determine the tensile strength of concrete [1][2][3][4][5][6][7][8][9][10][11][12]. Direct tensile test is first method for determination of tensile strength.…”
