摘要
为进一步研究冰材料的力学性能,基于冰试件的分离式霍普金森压杆实验,结合MAT10的拉格朗日算法与MAT155的SPH算法的适用性,开展了对应工况条件下冰动态压缩特性的ANSYS/LS-DYNA数值模拟,结果表明:应力应变曲线上结合MAT10的拉格朗日算法的模拟结果优于SPH算法,而SPH算法的冰模型破坏形态更接近实验结果。
In order to further study the mechanical properties of ice materials,the ANSYS/LS-DYNA numerical simulation of ice dynamic compression characteristics under corresponding working conditions was carried out based on the split Hopkinson compression bar experiment of ice specimens,combined with the applicability of Lagrange algorithm of mat10 and SPH algorithm of mat155, The results show that the simulation results of Lagrange algorithm combined with mat10 on the stress-strain curve are better than those of SPH algorithm,and the ice model failure mode of SPH algorithm is closer to the experimental results.
