Can Higher Strain Rates Be Modeled from Existing Stress/Strain Curves?

Click For Summary
SUMMARY

This discussion focuses on modeling stress/strain curves for higher strain rates using existing stress/strain data. The primary interest lies in the mathematical formulation necessary to generate a Dyna Material card, specifically for simulating the nominal stress/strain response of materials under high strain rates. Participants clarify that the discussion does not pertain to the intrinsic stress/strain behavior of materials but rather to the application of nominal high strain rates to a bar.

PREREQUISITES
  • Understanding of stress/strain curve analysis
  • Familiarity with Dyna Material card creation
  • Knowledge of high strain rate testing methodologies
  • Mathematical modeling techniques for material behavior
NEXT STEPS
  • Research the mathematical formulations for generating Dyna Material cards
  • Explore high strain rate testing techniques and their applications
  • Study the effects of strain rate on material properties
  • Learn about advanced modeling software for stress/strain analysis
USEFUL FOR

Material scientists, mechanical engineers, and researchers involved in high strain rate testing and simulation modeling will benefit from this discussion.

I want to create stress/strain curves for Higher Strain Rates from an available stress/strain curve?
I am interested on the mathematical formulation aspect to generate a Dyna Material card.

You are not talking about the intrinsic stress/strain behavior of the material, correct? You are talking about applying a nominal high strain rate to a bar and trying to determine the nominal stress/strain response, correct?
