Summary
This study derives macroscale equations for cartilage electro-chemo-hydro-mechanical processes using periodic homogenization. The findings are compared to existing thermodynamical approaches for cartilage modeling.
Area of Science:
- Biomechanics
- Biomaterials Science
- Computational Modeling
Background:
- Cartilage tissue exhibits complex electro-chemo-hydro-mechanical (ECHM) behaviors.
- Understanding these behaviors is crucial for diagnosing and treating joint diseases.
Purpose of the Study:
- To derive macroscale governing equations for ECHM processes in cartilage.
- To apply the periodic homogenization technique for multiscale analysis.
- To compare the derived equations with existing thermodynamical models.
Main Methods:
- Recalled microscale equations governing ECHM phenomena.
- Applied periodic homogenization technique to upscale physics from microscale to macroscale.
- Compared derived macroscale equations with established thermodynamical approaches.
Main Results:
