Dear Mojtaba Abdolkhani,

It is preferable to use a modulus of plasticity in the simulation of samples made by selective laser melting of 316L in a vase. This way, the simulation results will be closer to your experimental data. The use of foreign data will lead to deviations, which you will then have to specify with correction parameters. The connections obtained from the laser fusion have a strong influence on the mechanical characteristics and plasticity of the obtained products. Therefore, make standard test specimens by selectively melting the 316L. The obtained data, plasticity model and reinforcement curves are included in the simulation.

Wishing you success in your research.

Dear Mojtaba Abdolkhani

I suggest you consider an RVE (representative volume element) with a microscale in analysis. after applying the loads and boundary conditions you can use the hardening method in your analysis.

Dear Mojtaba Abdolkhani

We have recently used crystal plasticity simulations

for residual stress in AM 316L stainless steel.

Preprint Crystal plasticity model of residual stress in additive manufacturing

Code is openly available

and it is based on the MOOSE framework.
