When the rods are perpendicular to each other, there is no change in the area for small deformations and Poisson’s ratio is 1. However, as the rods are bent with an acuter angle, Poisson’s ratio increases, and the area decreases (Hearle et al., 1969) [3]. While analyzing the mechanical behavior of plain
