Tumor cellularity and volumetric results for constitutive model simulation study comparing linear elastic and neo-Hookean hyperelastic biomechanical coupling. Cellularity numbers are normalized by 1 × 109 tumor cells and volumes are expressed as cm3. Percent difference is expressed relative to the linear elastic model.
