Effect of friction on subsurface stresses in sliding line contact of multilayered elastic solids

A numerical integral scheme based on Fourier transformation approach is employed to investigate the e}ect of friction on subsurface stresses arising from the two!dimensional sliding contact of two multilayered elastic solids[ The analysis incorporates bonded and unbonded interface boundary conditions between the coating layers[ Two line contact problems are presented[ The _rst one is the contact problem between a rigid cylinder and a two!layer half space and the second one is the indentation of a multilayered elastic half!space by a ~at rigid punch[ The e}ects of the surface coating on the contact pressure distribution and subsurface stress _eld are presented and discussed
