Abstract

In structures joined by bolted connections, bolts are the most critical components of the assembly, with thread tearing being one of the most significant failure modes. This work presents an analytical and numerical modeling of the stresses in screw threads using finite element analysis. The results show consistency between the two methods, although simplifications were adopted in this study.
