A simplified method for estimating damping of joined plate structures with partial overlap region

Abstract: Mechanical joints such as bolted and spot welded joints are widely used to join plate structures. The existence of contact interface in the joint increases the vibration damping in the structure because the energy dissipation due to friction occurs at the interface. In this paper, we propose a procedure for calculating the energy dissipation at the interface using finite element analysis to estimate the damping for the fundamental and the higher modes. We use the static contact analysis instead of the dynamic … Show more

“…Nanda et al conducted plenty of researches on the first-order bending damping of the two overlapped steel plates [12]. Hirai et al constructed the three-dimensional model of the lap joint and studied the energy dissipation and damping characteristics of the bending vibration modes of the lap joint [13]. But he simplified the joint as a rigid element ignoring the effect of the preload on the modal damping.…”
