This chapter presents design formulae and methods for predicting the distribution of frictional forces and microslip over continuous or discrete contact areas between elastic bodies subjected to any combination of applied tangential forces and moments. The potential areas for fretting due to fluctuation of load without gross slip are discussed. The analysis of the contact between elastic bodies has long been of considerable interest in the design of mechanical systems. The evaluation of the stress distribution in the contact region and the localized microslip which exists before the applied tangential force exceeds the frictional resistance are important factors in determining the safe operation of many structural systems. Hertz 1 established the theory for elastic bodies in contact under normal loads. In his theory the contact area normal stress distribution and rigid body approach in the direction of the common normal can be found under the assumption that the dimensions of the contacting bodies are significantly larger than the contact areas. Various extensions of Hertz theory can be found in the literature 2 15 and the previous chapter gives an overview of procedures for .
