The Method of Accounting of Elastic Deformation Occur during the Automated Ball IndentationTest

Co-authors ANISIMOV Evgeniy

The influence of indenter’s elastic deformation on the measurement of mechanical properties of materials by automated ball indentation test (ABIT) and its interpolation for different loads (up to 10 kN), modulus of elasticity (up to 203 GPa), Poisson coefficient (up to 0,34) are discussed. The logging of indentation load (applied directly to the indenter), indentation depth and plastic depth against the time is done using electrical method. It was also found by finite element analysis (FEA) that Poison coefficient doesn’t affect the elastic deformation of indenter and the measurement process itself.
