Abstract

Although mechanical joints are integral parts of most practical structures, their modeling and their effects on the structural dynamics are not yet fully understood. This represents a serious impediment to accurate modeling of the dynamics and to the development of reduced-order, finite element models capable of describing the effects of mechanical joints on the dynamics. In this work we provide an experimental study to quantify the nonlinear effects of a typical shear lap joint on the dynamics of two structures: a beam with a bolted joint in its center; and a frame with the bolted joint in one of its members. Both structures are subjected to a variety of dynamical tests to determine the nonlinear effects of the joints. The tests reveal several important effects on the effective stiffness and damping effects of the lap joints. The possibility of using Iwan models to model the experimentally observed joint effects is discussed.
