Abstract
Coupled poroviscoelastic models, that are widely used to investigate biomechanics of hydrated soft biological tissues, may present distinct coupling strength arising from constitutive and geometrical parameters of each particular case. Regarding the coupled solution, the present study compares the effects on the computational performance of the monolithic and four iteratively-coupled solution schemes in the loading evolution controlling case within the context of soft biological tissues. To this end, a three-dimensional finite element model representing a force controlled confined compression was performed. The results highlight that the fixed-stress scheme and the monolithic one are well-suited methods for numerical experiments involving stress field control.
