I am using the LAMMPS (3 Mar 2020). I am trying to get the engineering stress-strain curve for a uniaxial deformation case. I am using “real” unit, with timestep equal to 1. But, due to limited computational resources, I have to apply a very high deformation rate. I have two questions:
- How can we relate the stress-strain response output with that of a much lower (real-world) strain rate? (Since my material is rate-sensitive)
- Is metadynamics the only way to address this issue or is there an alternative approach?
Please let me know if you need more information.
I look forward to hearing from you soon. Thank you very much in advance for your time and help.
With best wishes,
