... of a single cell. The model, derived from the standard linear solid model, consists of a Maxwell element in parallel with a spring with spring constant k 1 (Fig. 2b ). The Maxwell element consists of a dashpot with relaxation time τ r and a nonlinear spring with spring constant k 2...

... of these cells was modeled using the punch problem and standard linear solid. The punch problem yielded a Young’s modulus of 1.11±0.48 kPa. The standard linear solid model yielded an instantaneous elastic modulus of 8.00±4.41 kPa, a relaxed modulus of 1.09±0.54 kPa, an apparent viscosity of 1.50±0.92 kPa-s...
