“…Such an approach was proposed and exploited in the context of simplified inelastic analyses of shot-peening or similar processes, like in Zarka et al (1980), or Inglebert and Frelat (1989). Some generalizations are still under development.…”

“…Section 2 briefly presents the elastoplastic contact model developed by Mayeur et al [40]. This model is based on the direct stationary method proposed by Zarka et al [41] and Inglebert et al [42,43] to determine the stabilized state of the material under cyclic loading. It is used to determine the contact pressure distribution, the asperity plastic deformation and the subsurface stresses.…”

Quantifying the surface roughness evolution in contacts is a crucial step in the fatigue prediction process. Surfaces are initially conditioned by the running-in process and later altered by surface fatigue. The aim of this study is to understand and predict the evolution of the micro-geometry in the first few overrolling cycles. Numerical predictions are validated by experiments. A major difficulty in understanding surface degradation is the measurement of the surface roughness evolution at the relevant scales. A twin disc micro-test rig, called μMag, was specially designed for this kind of analysis. The μMag allows the "in situ" observation of changes in the disc surface during interrupted tests, thus avoiding dismounting the specimens, which is a major cause of inaccuracy. The new method also maintains the relative position of the two discs. The precision of the measurements allows one to use the initial surface microgeometry as input for the numerical contact calculation. Thus, the plastic deformation of the surfaces can be measured during the first cycles and compared to the numerical prediction. Results show a very good agreement between numerical predictions and experimental measurements.

“…The elastic-plastic model proposed by Zarka [17] was adapted by Guechichi [18] and Slim [19] to describe the formation of the residual stresses due the shot peening. Later, Fathallah [20] complemented these models, considering most of the process parameters, and reached good correlation with experimental data.…”
