CHANGES IN MATERIAL CLASSIFICATION OF THE URINARY BLADDER WALL AFTER SPINAL CORD INJURY

摘要

Changes in the mechanical properties of the urinary bladder wall following neurogenic disease or trauma can result in bladder dysfunction. We have recently reported changes in the biaxial mechanical properties of the bladder wall 10 days after spinal cord injury in a rat model Development of a constitutive model to characterize these changes would facilitate quantitative comparisons and provide the necessary information for organ-level computational modeling. However, before an appropriate constitutive model of the bladder wall can be formulated, its material class must be identified. In the present study, we applied a generalized method for material classification of biaxial mechanical data to our previous data on the urinary bladder wall.
