%X Dymanic fracture toughness K_(ID) was measured for 35CrMnSiA, PCrNiMo and No. 45 steel with CT-Specimen on a fracture testing mechine Testing results were compared with stat-ic K_C and K_(ID) was shown lower than K_(IC) in general. A transient memorizer was used to store wave form signals and a microcomputer is used to conduct data processing, results printing and curve plotting for higher efficiency and accuracy.
