Abstract: Due to the ongoing interest in novel negative Poisson ratio (NPR) materials, this study examines the buckling and postbuckling behavior of sandwich-structured composite toroidal shell segments (TSS) with graphene origami ...

Abstract: Negative Poisson’s ratio (NPR) auxetic metamaterials are attracting significant attention because of their peculiar and interesting mechanical features. Using geometrically von-Karman nonlinear factors and Mindlin plate ...
