| Abstract: | The electro-hydraulic servo testing instrument and the longer swing hammer dynamometric shock testing machine were used to measure dynamic fracture toughness KId of 35CrMnSiA steel. The condition of different size samples to satisfy status of plane strain and effect of strain rate to KId were studied. |
