Description:
This webinar presents an introduction to biphasic materials for modeling porous media mechanics in FEBio. This first webinar on biphasic theory focuses on its description of tissues as mixtures of a deformable porous-permeable solid matrix and an interstitial fluid. An overview is given of representative responses of biphasic materials to loading, especially in relation to interstitial fluid pressurization and flow. A description is provided of the governing equations, required constitutive models for the solid matrix stress and the hydraulic permeability that governs interstitial fluid flow, associated material properties, and essential and natural boundary conditions needed to solve biphasic problems. Guidelines for creating biased meshes at free-draining boundaries are provided. Several representative biphasic analyses are also reviewed.
