ABSTRACT
The nonlinear dynamic behavior has an important impact on energy dissipation and vibra-
tion damping characteristics of bolted joints. Firstly, the development of tangential dynamic
models is summarized and analyzed. Secondly, a five-parameter Iwan model based on a trun-
cated power-law distribution is proposed. The backbone and hysteresis curves are obtained.
Thirdly, normalized and dimensionless analysis is performed. On the basis of the above,
a more concise four-parameter Iwan model with stiffness continuity is proposed. Finally,
the validity of the model is verified by comparing the energy dissipation vs excitation force
amplitude curve with the experimental data.
