LARGE STRAIN ANALYSIS OF 3-D VISCOELASTIC SWELLING OF CHARGED TISSUES AND GELS

摘要

Materials like soft biological tissues undergo large viscoelastic deformations during the swelling process. Following this, it is the goal of this contribution to merge the advances of finite viscoelasticity laws and the state of the art in electrochemical swelling theories within a well-founded multiphasic concept. The numerical treatment is carried out fully 3-d in the framework of the FEM.
