(Top) Distortion problems in elastomeric materials during stretching and distortion-free stretching

(Bottom) Typical elastomer with Poisson's ratio of 0.5 (severe vertical contraction, left), and aligned fiber composite for controlling Poisson's ratio near 0 due to the high stiffness of fibers resisting vertical contraction under strained states (right).
