Unified theory of indentation hardness HIT in Instrumented Indentation Test : I.I.T. for Vickers & Berkovich indenters introducing indenter's shape correction factor β in case of Tangent depth method (2nd. Calculated values of the indentation hardness HIT & HIT(β ) with the experimental data for the test force Fmax from 10 [mN] to 1960 [mN] using the Unified theory)
