Rate-Dependent Constitutive Modeling of Soft Tissue for Surgical Simulation

Quick fact

Soft tissues like skin and liver are viscoelastic: their stiffness changes with the speed of deformation, so a fast poke feels firmer than a slow press. Surgical simulators must capture this rate dependence to train surgeons effectively.

Why this is interesting

You've probably noticed that poking your cheek quickly feels different from pressing slowly—why do tissues respond so differently to speed? This question lies at the heart of making surgical simulators feel realistic.
