| 中文摘要 | In order to obtain the dynamic shearing property of high N alloy steel, the plugging test was performed by using the improved Hopkinson pressure bar system. As dynamic shearing strengths, the dynamic shearing energies during plugging process of two type high N alloy steels were determined from the shearing constitutive relationship at different super high strain rates. According to the theory of dislocation dynamics in Seeger equation, a dynamic shearing damage constitutive relationship was established and the different parameters of this material were determined by using the curve fitting method. The measured results indicated that the dynamic shearing property of high N alloy steel could be obtained effectively by the improved Hopkinson pressure bar system, and the effects of strain rate could be simulated by dynamic shearing damage constitutive relationship. |
