In this tutorial, the Simulation sandstone cutting by using a rigid tool in Abaqus-Damage investigation – has been studied. The stone part is modeled as a three-dimensional solid part. The tool is imported to the Abaqus as a deformable part, but in the interaction section, the rigid constraint has been used for it. You can see a figure of the assembled parts below
To model sandstone behavior under severe load in Abaqus, the JH2 model is appropriate. The JH-2 constitutive model was initially utilized to simulate the behavior of brittle materials, especially ceramics. the JH-2 model adds softening characteristics and contains pressure-dependent strength, damage, and fracture; significant strength after fracture; bulking, and strain rate effects. The parameter determination for the JH-2 model is not a straightforward process as some of the constants cannot be determined explicitly. In the JH-2 constitutive model, HEL is an important concept throughout the whole computational process. Before determining the parameters of the JH-2 model, it should be noted that the normalized parameters are all derived based on the constants concerned with HEL. That material can be used as an input file or VUMAT code. The explicit step is appropriate for this type of analysis. In order to reduce the time of the simulation, the mass-scale technique is used. The general contact interaction with internal element erosion is considered by using an editing input file. The fixed boundary condition is selected for two sides of the sandstone and axial displacement and rotational velocity for the tool. The mesh should be fine to achieve good results
After the simulation, all results such as damage, failure, stress, strain, and…are achievable. You can see some figures for the results below
