Nanoindentation derived stress–strain properties of
2007-7-1 · Methods. A nano-based indentation system (Ultra Micro-Indentation System, UMIS-2000, CSIRO, Australia) was used to determine the indentation stress–strain response of two kinds of dental ceramics (Cerec ® 2 Mark II and Vita VM9), one kind of dental alloy (Wiron ® 99) and healthy enamel. A spherical indenter was used to test the materials with nanometer and micro-Newton displacement and ...
