author keywords: cartilage; osteoarthritis; cell mechanics; chondrocyte; mechanotransduction
MeSH headings : Biomechanical Phenomena; Chondrocytes / physiology; Chondrocytes / ultrastructure; Elasticity; Linear Models; Microscopy, Video; Models, Biological; Numerical Analysis, Computer-Assisted; Predictive Value of Tests; Suction / instrumentation; Viscosity
TL;DR: An axisymmetric boundary integral formulation of the governing equations of incompressible linear viscoelasticity is presented and used to simulate the micropipette aspiration contact problem and predicts an aspiration length that is less stiff during the initial ramp response but more stiff at equilibrium.
