Computational results showing how tissue softening influences thinning and dilation.

gr = 0.1, gθ = 2, and gz = 1. Tissue softening is represented by decreasing the shear modulus μ or the fiber stiffness γ. When μ decreases (γ = 1000 Pa, the original fiber stiffness), thickness increases slightly and r1 decreases slightly, i.e., both thinning and dilation are weakened slightly. When γ decreases (μ = 1650 Pa, the original shear modulus), thickness decreases slightly and r1 increases slightly, i.e., both thinning and dilation are strengthened slightly.
