Abstract

The development of a 3D finite element model for charged hydrated soft tissue containing charged/uncharged solutes was carried out based on multi-phase mechano-electrochemical mixture theory. The mechanical, electrical and chemical signals within human intervertibral disc under mechanical loading were analyzed using the model. A decrease in initial tissue water content increased the peak stress and relaxation time due to reduction of permeability, causing greater fluid pressurization effect. The results of the analysis provide additional insights into the load-supporting mechanisms and physical signals within human disc.
