This investigation was conducted to propose an estimation method for energy dissipation in riveted lap joints. In this study, we made a simple energy dissipation model for riveted lap joint by replacing the joint part with a material that draws a hysteresis loop. This simple model does not require detailed contact analysis. Therefore, the calculation cost can be reduced. Hysteresis loops were obtained from cyclic loading tests. Coefficients were obtained by fitting the hysteresis loop assuming that the shape of the hysteresis loop is symmetric. The coefficients were applied to FEM as material properties. Then, load/displacement curves were obtained from FEM, and energy dissipation was calculated from the hysteresis loop. It was shown that the simple model in this study can reproduce the energy dissipation process with an error of less than approximately 13% in the range of the experiment.
