Tension of an Elastic Circular Cylinder with a Rigid Spherical Inclusion : Effects of Negative Poisson's Ratio

Abstract

This paper investigates on the effects of Poison's ratio, especially effects of negative Poisson's ratio, on stress concentrations of an elastic solid circular cylinder with a rigid spherical inclusion under tension. Lakes has shown that there are materials with negative Poisson's ratios. It is said theoretically that values of Poison's ratio may take from ν=-1.0 to ν=0.5.
