- •
The indentation imprints were analyzed to study the plastic behavior of coatings.
- •
A finite element method in conjunction with nanoindentation tests was applied.
- •
Validation of simulation with experimental maximum loads resulted in multiple solutions.
- •
The flow curves of HPPMS CrN, AlN and CrN/AlN-multilayer coatings were simulated.
- •
Nanostructured CrN/AlN showed high resistance against plastic deformation.
