Through a series of simulations of instrumented indentation, contour plots of several parameters, as maximum load, contact hardness and contact stiffness, were computed. By superposing them pair-wisely, RS and PP mixed together could be characterized simultaneously. In order to verify the method, several simulations with different combinations of RS and PP were performed. Results showed that the method is promising but remains to be tested on experimental acquisitions. %G English %L hal-02276251 %U https://utt.hal.science/hal-02276251 %~ ONERA %~ CNRS %~ UNIV-TROYES %~ UTT
