Abstract

With the rapid development of computer technology, numerical simulations of rock dynamics have been widely carried out. The accuracy of numerical simulations depends on the parameters of the constitutive model. In this paper, the parameters of a Johnson–Holmquist-II (JH-2) constitutive model for granite were determined. First, mechanical and penetration tests were carried out on granite specimens. The mechanical tests included a quasi-static compression test and Brazilian disc splitting test to obtain the basic mechanical parameters and failure modes of granite under impact loading. Then, using the experimental results combined with the existing literature data, the parameters of the JH-2 constitutive model were determined through theoretical derivation. Finally, by comparing the numerical simulation results with the test results, the validity of the parameters was verified. These parameters can better simulate the mechanical response and failure modes of granite under different loads. The material model parameters can provide references for subsequent experiments and related numerical simulations.

Highlights

  • The parameters of a Johnson–Holmquist-II (JH-2) constitutive model for granite were obtained.

  • Various mechanical tests and penetration tests were performed on granite.

  • The model parameters have a wide range of applications.
