An additional challenge to bonding TPE is that its superior flexibility results in a strong Poisson effect
In most cases the pipe strain is minimal and although there is some elongation (see Poisson effect
) on an HDPE pipe as it is installed, that strain will be well below the safe pulling allowance of the pipe.
Second, there is an increase in the anterior-posterior dimension of the spinal cord due to the Poisson effect (3).
The Poisson effect relates to elastic structures of a fixed volume which alter their cross-sectional diameter when stretched (3).
Paper  offers the methodology for the multilayer two-phase rectangular bar stiffness estimation with the account of Poisson effect. The proposed methods in papers [14-15] allow determining the contact pressure and axial stress in case of the two-layer cylindrical bars.
The aim of this work is to calculate stresses on cylindrical MB's and with regard to Poisson effect, to examine its influence on stress, stiffness and errors produced in case of neglecting this effect.
Naaman  and Bentur  considered the Poisson effect
in their pull out model.
The finite element model developed for this project did not indicate a significant influence of a Poisson effect
on observed tensile stiffness values.
As mentioned above, the increased variability due to the presence of the aggregate masks any Poisson effect
when averaging over several repetitions at a given horizontal resolution.
