Finite element investigations of the fluid-solid behaviour in a bio-inspired poroelastic bearing

Poroelastic materials are commonly found in biological systems, such as articulating cartilage, and the ability to predict their biphasic behaviour is a key step understanding of joint health development biomimetic devices. Here, fully coupled three dimensional finite element study presented demonstrate permeability dependent load carrying capacity fluid pressure time-varying poroelastic system. A bio-inspired material model demonstrated with relaxation simulations which first show results for cartilage-like sample then variation from [Formula: see text] text]. The rate non-linear but total time scales linearly permeability. That context mechanical bearing operating lubricated contact an impermeable wall. that given set conditions modifies how solid phases accommodate applied loads. High support varies through thickness width bearing. It particularly high around regions where interstitial flow restricted by external factors interfaces. offers novel method local pressures stresses within material.
