For polymethyl methacrylate(PMMA),dynamic fracture tests were conducted by using central notched circular disk specimen in the split Hopkinson pressure bar.
采用尖槽式中心切口圆盘试件,在分离式霍布金森压杆试验装置上对有机玻璃纯Ⅰ型和纯Ⅱ型加载条件下的动态断裂行为进行了实验研究。
For polymethyl methacrylate(PMMA),pure mode I fracture tests were performed under quasi-static loading by using central notched circular disk specimen.
采用直槽式和尖槽式中心切口圆盘试件,对有机玻璃在纯Ⅰ型准静态加载条件下的断裂行为进行了实验研究。
