📄 Detailed description
This paper deals with the mechanical behavior of soft living tissues under
load-unload and relaxation cyclic strains. It proposes a thermodynamic model
formulated within the Generalized Standard Materials framework that incorporates
both Mullins’ effect and viscoelasticity, integrating the history dependent
behavior of the material under finite strain. A key innovation lies in the use of a
common softening function to modulate both the hyperelastic and viscous components,
capturing history-dependent behavior more accurately. Viscous parameters
are adjusted based on the loading history via the maximum strain invariant.
Numerical implementation is validated against uniaxial tensile tests on porcine
perineal tissues and a global Sobol sensitivity analysis confirms that elastic, viscous,
and Mullins-related parameters are identifiable from different phases of the
loading protocol. This model provides a unified, thermodynamical consistent tool
for simulating soft tissue mechanics.
