Interlayer Slidable Friction Structures on SoftSubstrate

Abstract

In this paper, we consider the interlayer slidable friction structures on softsubstrate as the hardcover booklikelaminatedplates with internal friction on the Winkler foundation. For a quasistatic problem, a detailed analysis of the bending response and energy dissipation is carried out for a threepointsupported layered plate on the Winker foundation. Our numerical investigations show that the hardcover, friction, and substrate have a great influence on bending response, and in particular, the friction can cause a considerable amount of energy dissipation within per loading–unloading cycle. The study is not only to predict the mechanical interactions behavior inbetween of geometry, friction, elasticity, and substrate but also as a representative case to help finding some clue on the universal behaviors of interlayer slidable friction structures on softsubstrate.
