Constitutive Modeling of Time-Dependent Response of Human Plantar Aponeurosis
Figure 3
Average experimental data (open circles) and SD for the samples taken from the plantar aponeurosis of one of the donors, as normalized stress versus time. The numerical solutions refer to a viscoelastic model with one, two, and three viscous branches. The stress relaxation is reported up to 10 s (a) and for the whole relaxation process (b).
