1)  flattened Brazilian disc
平台巴西圆盘
1.
It is in this background that the displacement formula of flattened Brazilian disc for orthotropic material is proposed.
改进后的平台巴西圆盘克服了集中力产生应力集中的缺点,正交异性材料则是对各向同性材料的推广,在这样的背景下提出正交异性巴西圆盘试样的压缩位移公式。
2.
In order to investigate the dynamic tension strength of rocks,the flattened Brazilian disc specimens were subjected to diametral impact with different projectile speeds by using the split Hopkinson pressure bar(SHPB) of 100 mm in diameter where a thin aluminum circular plate was used as a pulse shaper.
利用直径100 mm的Hopkinson压杆和薄圆形铝片作为波形整形器,用不同弹速径向冲击平台巴西圆盘试样以研究大理岩的动态拉伸强度。
3.
The dynamic split tests of marble using both Brazilian disc and flattened Brazilian disc were performed at high strain rate with split Hopkins pressure bar(SHPB) of 100mm diameter.
首次把平台巴西圆盘试样引入动态劈裂试验。
2)  flattened Brazilian disk
平台巴西圆盘
1.
Study on modificatory coefficient in tensile strength formula for flattened Brazilian disk specimen;
平台巴西圆盘抗拉强度公式修正系数的研究
