EXPERIMENTAL STUDY ON THE PLANE STRAIN DYNAMIC FRACTURE TOUGHNESS OF 20CRMNTI BASED ON IMPROVED HPB PLATFORM
To obtain the dynamic fracture toughness of 20 Cr Mn Ti,an impact loading test was conducted on three-point bending specimens with the improved Hopkinson pressure bar.Dynamic stress intensity factor was determined by the spring mass model.The onset time of crack initiation is experimentally detected...
