The material constitutive relationship is not only the conclusion of some regulations summarized from experimental data, but also plays an important role in numerical simulations. It reflects the realistic physical and mechanical properties of materials as much as possible to improve the accuracy of numerical results. At present, various kinds of constitutive models for materials are being developed and being optimized constantly along with an increasing need for numerical simulations. Especially for those materials under the loading conditions of large strains, high strain rates, and high pressures (LHH), dynamic constitutive models usually contain more complicated parameters of physical properties and some sensitive coefficients such as various rate effects and strength coefficients , so that the parameter determination becomes an increasingly difficult problem. Therefore, accurate parameter determination for material constitutive models, which may directly affect the reliability and validity of the analytical results in numerical simulations, has become a significant task.
In this simulation the granite is modeled as deformable part and projectile as rigid body. The material model which used in this simulation has good performance to show damage variable for granite. Dynamic explicit is appropriate for this analysis. Mesh quality is a other items which has effect on result and you can see some figures of this simulation at below
