TEODORESCU, M. ... et al, 2009. Harmonic decomposition analysis of contact mechanics of bonded layered elastic solids. Applied Mathematical Modelling, 33 (1), pp. 467-485.
The paper presents an iterative method for obtaining footprint, pressure distribution, local deformation and sub-surface
stress field for the contact between a rigid cylindrical indenter and an elastic flat substrate. The methodology is applicable
for semi-infinite, as well as for thin or thick bonded elastic layered solids with high or low elastic moduli. All findings are in
accord with the observed behaviour of hard wear resistant and soft solid lubricating coatings. It is shown that the decomposed
contact pressure distribution into a series of harmonic waves induces sub-surface stress fields that decay into the
depth of the solid according to their wavelengths. Consequently, conditions vis-a`-vis fatigue spalling and adhesion performance
may be predicted for given thickness of layered bonded elastic solids.
