Abstract

Abstract

The numerical simulation was carried out for the dynamic response of crack subjected to the normal, shear and oblique impact loads. The dynamic stress field and the strain field were obtained. According to its definition, the corresponding dynamic stress intensity factor (DSIF) was calculated. The situation of initiation of crack impacted by oblique loads was analyzed, and the optimization fracture by stress pulses was discussed.
