The dislocation-based crystal plasticity model for Aluminium (nonlocal_Al) in DAMASK has several parameters. Which parameters should be modified to match the experimental and simulated tensile stress-strain curve?
I am attaching the model parameters file for the reader's reference.
DAMASK, or the Düsseldorf Advanced Material Simulation Kit, is a software that enables the simulation of the mechanical properties of crystalline materials based on crystal plasticity. The nonlocal_Al model in DAMASK is a dislocation-based crystal plasticity model for aluminium.
If you're trying to match the simulated results from this model to experimental tensile stress-strain curves for aluminium, you may need to modify the following parameters:
Note: Changes to these parameters should be based on experimental data or literature values where possible. Remember, when changing one parameter, others might need to be adjusted as well because of their interdependencies. It's also worth noting that it may not be possible to achieve a perfect match between simulation and experiment due to the inherent simplifications and assumptions in the crystal plasticity model.
