...., pressures of 0.0–1.0 MPa). The video images recorded during the tests were analyzed to determine whether or not fluid exchange between the PDL and the surrounding medium took place during mechanical loading. A value for the tissue’s apparent Poisson ratio was also determined. The following observations were...

... have subsided. In particular, this model can predict the transition of Poisson’s ratio from very low values in compression ( ∼ 0.02 ) to very high values in tension ( ∼ 2.0 ) . Most of these phenomena cannot be explained when using only three orthogonal fiber bundles to describe the tissue matrix...

... contact elements. This ensures the rigid bonding between the needle and the gel. The modulus value for the gel is taken as Young’s modulus obtained from the bead test for each of the three gels, and Poisson’s ratio of 0.49 is taken assuming the gel to be nearly incompressible ( 26 27 ). The force...
