Nanoindentation of flexible graphite: experimental versus simulation studies
Abstract
Nanoindentation corrected for thermal drift has been performed on binderless flexible graphite with a Berkovich tip, and the numerical modelling of the results has been carried out. The nanoindentation load-displacement curves of the samples were obtained under different peak loads ranging from 100 µN to 1 mN. Finite Element Method was applied for analysing the loading and unloading parts of these curves, using an elasto-plastic model and assuming flexible graphite as a continuous medium. The difficulties in determining the mechanical properties of binderless flexible graphite from the nanoindentation load-displacement curves were discussed. Numerical results were compared to experimental nanoindentation curves, and some mechanical parameters of this material were determined for the first time.
