Numerical Simulation Research of SHPB Experiment of Oil Well Cement Stone Based on HJC Model
In this paper, the HJC model parameters of oil well cement stone are determined by experiments, and the SHPB experiment process of materials is simulated by finite element software. The result shows that: 1) The HJC model can effectively describe the constitutive relation and failure mode of oil well cement stone under the impact loading; 2) As the strain rate increases, the compressive strength of oil well cement stone increases too, but Young's modulus change less obviously; 3) Under uniaxial impact, with the increase of loading rate, the fracture degree of oil well cement stone increases too, and the fracture surface is approximately parallel to the load direction, which is mainly tensile failure; 4) For oil well cement stone with different mix proportions, only a small amount of parameters in this paper need to be adjusted through uniaxial compression experiments.
