Indentation device, instrumented measurement system, and a method for determining the mechanical properties of materials by the indentation method

The instrumented indentation measurement system includes an indentation device, a loading mechanism, a table for the sample, an analog-digital converter and a computer. Inside a housing of the device there is arranged a holder for a displacement sensor, rigidly connected to the housing. Slidably positioned rod passing to the displacement sensor is arranged in the holder in the axis of the indenter. A pushing segment is equipped with supports engaging with a central pressure plate arranged slidably in the housing a lower pressure plate is arranged slidably in the housing and connected with the holder of the indenter. A first resilient member, a central pressure plate and the lower pressure plate are provided with holes for passage of the rod to the holder.
