Abstract

In case of applying axial tensile force to a high strength bolt, in general, stress is concentrated at the bottom of the threaded portion. As a result, its failure mode is brittle due to lack of ductility. In this study, the mechanical behavior of high strength bolts with waisted shank subjected to axial tensile force has been analyzed numerically by FE analysis considering both material and boundary nowlinearity. Based on these numerical results, an optimal diameter of the waisted shank of the bolts is discussed paying attention to their energy absorption capacity.
