Zum Nachweis einiger mechanisch-rheologischer Eigenschaften des hyalinen Knorpels

Summary

Experiments on hyaline cartilage have demonstrated the complex mechanical behaviour of this tissue, which can be delineated with consideration of the rheology and physics of high polymers with technological methods of testing for organic materials. The mechanical loadings preceding the actual test (preconditioning) have, according to the length of the intervals, an influence on the actual histomechanical test. Constant cyclic loadings of limitted force are reproducible according to the degree of preconditioning. The shape of force-recovery curves and the size of mechanical recovery (force regain) depend on the extent of unloading. After constant amplitudes of unloading within different fields of force, there occur relaxations, isorheological straight lines with secondary relaxations or force recovery curves dependent on the level of the field of force in which the axial deformation is kept constant.
