Simulation drilling process of the aluminum alloy in Abaqus

In this tutorial, the Simulation drilling process of the aluminum alloy in Abaqus has been studied. The tool is modeled as a rigid shell part and the aluminum part is modeled as a three-dimensional solid part. You can see a figure of the assembled parts below

To model aluminum behavior, the elastic-plastic material with ductile and shear damage model is used. The ductile model assumes that the equivalent .plastic strain at the onset of damage is a function of stress triaxiality and strain rate.The shear damage initiation criterion is a model for predicting the onset of damage due to shear band localization. The model assumes that the equivalent plastic strain at the onset of damage is a function of the shear stress ratio and strain rate. During the simulation, the tool can penetrate and remove the elements. The dynamic explicit procedure is appropriate for this type of analysis. The mass scale technique is used to reduce the time of the simulation and make stability in the model. The contact models in the Abaqus can’t consider the erosion and internal element failure, so the input file capability is used to model general contact to consider the erosion. The fixed boundary condition is assigned to the aluminum part and axial and rotational velocity to the tool. The mesh should be fine at the contact zone

After the simulation, all results such as tool penetration, stress, strain, damage, failure, and … are available. You can see some figures for the results below
