| 英文摘要 | It is well-known that the numerical value is always larger than the measured value, amounting to many times, if we calculate the stress of the specimen in the impulse test using the NASTRAN and ANSYS (N-A) software. We believe that the impact induces shock wave or quasi-traveling wave in the specimen, which can qualitatively explain the discrepancy of the two values. In order to verify it, the Lax-Friedrichs (L-F) scheme is taken to simulate the transmission of shock wave and quasi-traveling wave in solid. Numerical results show that the action area of the stress wave is small and the action time is very short, so the resulting stress and actual work are not big. In addition, the distribution of the impact values obtained by the numerical simulation is in accordance with the trend of the measured impact values. |
