Ultra High speed imaging of dynamic fracture in transparent Spinel ceramic

Ultra High speed imaging of dynamic fracture in transparent Spinel ceramic. The videos where film at frame rate of 2,5,7.5 and 8 milion frame per second. The Spinel bar, 3mm thick, is standing upright and unsupported. It is shock-loaded by a steel bar (Hopkinson) on the right hand side. The crack is initiated at the opposite left side, which is in tension.透明尖晶石陶瓷（Spinel ceramic）动态断裂过程的超高速成像数据集。该数据集包含的视频拍摄帧率分别为2、5、7.5及8百万帧每秒。厚度为3mm的尖晶石陶瓷棒呈竖直悬空状态，其右侧通过钢质霍普金森杆（Hopkinson）施加冲击载荷，裂纹起始于与之相对的左侧受拉区域。
