玻璃陶瓷（MACOR）拉伸强度率相关性的研究
Study on Rate Dependence of the Tensile Strength of Machinable-glass-ceramic（MACOR）
摘要
Abstract
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.关键词
