K. Mithraratne, H. Ho, P.J. Hunter and J.W. Fernandez Mechanics of the foot Part 2: A coupled solid–fluid model to investigate blood transport in the pathologic foot International Journal for Numerical Methods in Biomedical Engineering 28
A coupled computational model consisting of a soft tissue continuum and an embedded network of major arteries of the foot is developed to investigate blood flow under normal and pathologic conditions. The hydrostatic pressure distribution within the tissue is determined by its mechanical properties and acts on the external surface of the arteries. Simulation results reveal that a twofold increase in tissue stiffness results in about 28% reduction in blood supply to the affected region for the same loading conditions.
