Description
Fujiwara's team in Osaka modeled artery walls as sponges rather than sealed, incompressible tubes. Tests show artery volume can shift by a tenth or more under load. Their biphasic framework couples a stretchy solid skeleton with moving tissue fluid. Cut to one radial dimension, the model ran as finite blocks.
Modeled warps matched test averages within two percent. Fluid pressure inside the wall explained the seeming squash on its own. That pressure also builds hidden outward tension in the solid frame. The authors offer the framework for settings where fluid-solid interplay matters.
