Abstract
In this paper a generic micromechanical modelling approach is introduced that allows for dynamical simulations of cellular biological tissue. It is derived from the discrete element approach in the sense that the tissue is discretised such that microscopic features and histological aspects like cell geometry and the cellular arrangement within the tissue can be fully incorporated into the model. This makes dynamical simulations of arbitrarily shaped cellular tissues feasible in an elegant and robust way, while providing room for future extensions to incorporate intercellular fluid transport and tissue failure. The validity of this simulation technique is demonstrated by a case study on the unicellular epidermis layer of the Spanish onion (Allium cepa). The parameters of a two dimensional model are determined using the stress-strain relation in a tension test for longitudinal strips. The model is then validated quantitatively against the data for transversal strips.
