Abstract

The specific design
of components like rotor and stator as sheet-layered lamination stacks results
in a structural behavior that is heavily dependent on the sheet interactions on
the microscale. Due to the manufacturing process, these thin laminations may be
just stacked and held together e.g. by welding or clamps, such that frictional
contact of rough surfaces between single sheets is taking place and
significantly affects the overall deformation behavior. Here, the elastic anisotropic, more precisely
transversely isotropic, material parameters describing these lamination stacks
are identified with the help of the homogenization taking efficiently care of
the microstructure. For this purpose, different constitutive contact laws in
normal direction capturing the sheet interactions by a penalty formulation and
their effect on the macroscopic quantities are presented to emphasize the
importance of this model parameter. Furthermore, it is shown that the derived
stress-strain relation is identical to results of a numerical homogenization,
where a representative volume element is simulated by the Finite-Element method
incorporating Zero-Thickness elements for the contact simulation. The numerical
results are finally compared to experiments showing a good accordance.
