| 摘 要： | 采用ANSYS/LS-DYNA非线性有限元程序,对Hopkinson层裂试验进行了数值模拟计算,并与实测结果做了对比。结果表明,ANSYS/LS-DYNA程序模拟输入杆的应变历程,具有较好的精度;模拟的砂浆混凝土长杆试件中的应变历程则存在一定的差异,并且分析了产生计算误差的原因。

| Abstract: | In the paper using ANSYS/LS-DYNA nonlinear finite element code,the spalling experiment of the Hopkinson bar is numerically simulated.Comparing the results of simulation with experiment,it is found that the strain of simulation in the incident bar tallies well with the results of experiment,and there is some difference between the numerical and experimental results in the mortar specimen.The reasons that lead to errors are analyzed. |
