The Brazilian disk(BD) test was used to investigate the rate dependence of the tensile strength of glass-ceramic Macor. The static measurement was conducted with a servo-controlled material testing machine and the dynamic experiment was carried out with a 6.35 mm diameter split Hopkinson pressure bar(SHPB) system. The pulse-shaping technique was used to achieve dynamic force balance, eliminate the loading inertial effect, and enable quasi-static stress analysis. The experimental results showed that the tensile strength of Macor is loading rate dependent, the tensile strength, as a function of loading rate, increases from 26 MPa to 50 MPa as the loading rate is increased from zero to 5 780 GPa/s.
