Abstract: The Naval Undersea Warfare Center has funded a project to
investigate the accuracy of various bolt models used to represent actual
shipboard bolted connections within an analytical shock survivability
assessment. The ultimate goal within this project is to develop finite element
bolt representations that are not only computationally efficient, but also
accurate. A significant task within this effort involved the development of
highly detailed finite element models of bolted connections under various load
configurations. Accordingly, high-resolution bolt models were developed and
incorporated into simulations of four bolted connection test arrangements:
static shear, static tension, dynamic shear, and dynamic tension. These
simulation results are validated against experimental data from physical
testing of each configuration. Future research will focus on exploring
simplified finite element bolt representations and comparing these against the
high-resolution results.
