Viscoelastic properties of bladder wall strips at constant elongation.

摘要: The experimental and data processing methods used were improved in several respects compared with those described previous publications. One hundred twenty-two stress decrease curves for bladder wall strips measured at constant elongation; reproducibility was tested. Consideration of the results led to addition two elements (a dashpot an active element) our model process involved. influence on measurements is mathematically analyzed terms increase rest length during stretch. could be successfully fitted parameters turned out physiologic range. Some recent models describe muscular relaxation tested criticized.
