ABSTRACT = {This paper deals with modeling of the phenomenon of fretting fatigue in
heterogeneous materials using the multi-scale computational homogenization technique
and finite element analysis (FEA). The heterogeneous material for the specimens consists
of a single hole model (25% void/cell, 16% void/cell and 10% void/cell) and a four-hole
model (25% void/cell). Using a representative volume element (RVE), we try to produce
the equivalent homogenized properties and work on a homogeneous specimen for the
study of fretting fatigue. Next, the fretting fatigue contact problem is performed for 3 new
cases of models that consist of a homogeneous and a heterogeneous part (single hole cell)
in the contact area. The aim is to analyze the normal and shear stresses of these models
and compare them with the results of the corresponding heterogeneous models based on
the Direct Numerical Simulation (DNS) method. Finally, by comparing the
computational time and % deviations, we draw conclusions about the reliability and
effectiveness of the proposed method.},
