The models introduced here will be pure mechanics models employing fairly simple constitutive laws for active and passive mechanics. Future extensions of the models may include a coupling to the electrophysiology and electro-diffusion models described in the other chapters, to study the impact of spatially heterogeneous ion concentrations on the cell and tissue mechanics.}, year = {2021}, journal = {Modeling Excitable Tissue: The EMI Framework}, volume = {7}, edition = {1}, chapter = {3}, pages = {28-43}, month = {11/2020}, publisher = {Springer International Publishing}, address = {Cham}, }
