Summary: The mechanics of stacked beams with interfacial friction are discussed. The particular example of two beams, simply supported and subjected to uniformly distributed loading is used to demonstrate an algorithm for computing load/deformation behavior and energy loss in such systems. It is demonstrated that the cross-sectional geometry of the beams affects the amount of energy lost to friction during loading, and it is suggested that this fact could be utilized in the design of slipping beam damping devices.
