Abstract
Deformation and elastic stress characteristics are considered for a thin elastic film on a rigid substrate when loaded by a rigid cylindrical indentor in conjunction with different amounts of friction. Friction tends to move the point of maximum shear stress from below the loaded surface into this surface, particularly when the elastic film is thin relative to the width of contact. Increased friction also increases the magnitude of the horizontal tensile stress (σx) in the free top surface and moves it closer to the trailing edge of the indentor. Friction has a rather negligible influence on the depth of deformation for a given loading condition but substantially increases the magnitude of the peak normal stress in the loaded surface and moves it toward the leading edge of the indentor.
