There is no buckling in the sample at all due to near frictionless specimen-compression platen interface. As for modelling, I have modeled a cylindrical disk as a neo-hookean elastic material and applied a uniaxial uniform displacement in the z direction upon the superior surface of the disk...

The cylinder axis is in the z-direction with applied uniaxial compression in the z also. Poisson's ratio may be an intrinsic material property, however, during experiments and FE modelling, I find radial variation (ie, along the x axis) with the highest value occurring at the circumferential...

Hi, I am wondering why radial variation in Poisson's ratio exists when a cylinder is compressed? Ie, Poisson's ratio toward the center is lower than what is measured at the circumferential edge. Thanks M
