Shear performance of NPR bolt under varying prestress levels

The negative Poisson’s ratio (NPR) bolt is an innovative support element distinguished by its high strength, elongation, and a slightly negative Poisson’s ratio. Unlike conventional prestressed (PR) bolts with a positive Poisson’s ratio, the NPR bolt exhibits a quasi-ideal plastic response without a...
