This study introduces a new method to optimize parameters for elastic models, enabling comparisons between models with non-transferable parameters. The approach focuses on the time-dependent behavior of these models for accurate equivalence.

Area of Science:

  • Materials Science
  • Computational Mechanics
  • Engineering

Background:

  • Comparing elastic models often requires parameter optimization when direct conversion is not feasible.
  • Many commonly used elastic models present challenges in parameter transferability.

Purpose of the Study:

  • To present a general method for optimizing parameters of elastic models.
  • To enable comparison and identification of equivalent behavior between diverse elastic models.

Main Methods:

  • Development of a general optimization framework.
  • Analysis of elastic model behavior over time.
  • Parameter tuning based on time-dependent responses.

Main Results:

  • Successful optimization of parameters for various elastic models.

Related Experiment Videos

  • Demonstration of equivalent behavior through optimized parameters.
  • Validation of the method for non-transferable parameter scenarios.

    • Conclusions:

    • The proposed method provides a robust approach for elastic model parameter optimization.
    • This facilitates accurate comparison and understanding of elastic models with disparate parameter sets.
    • The time-dependent behavior analysis is key to achieving model equivalence.
