THEORETICAL AND FINITE ELEMENT MODELS FOR COUPLED ELECTRO-MECHANO-CHEMICAL TRANSPORT IN SOFT TISSUES

摘要

A general theoretical and finite element model (FEM) for soft tissue structures is described including arbitrary constitutive laws based upon a continuum view of the material as a mixture or porous medium saturated by an incompressible fluid and containing charged mobile species. Example problems demonstrate coupled electro-mechano-chemical transport and deformations in FEMs of layered materials subjected to mechanical, electrical and chemical "loading" while undergoing small or large strains.
