MAIN

Application

       The laboratory testing machine "UTM-20 HT” is intended for studying process of indentation of specimens from constructional materials with the purpose of definition of their hardness characteristics, and also development of experimental techniques for strength characteristics estimation of  constructional materials (yield strength, ultimate strength, strengthening coefficient, tensile strain etc.). These techniques are based on the analysis of diagrams from continuous indentation registered during tests and has been developed in the G.S.Pisarenko Institute for Problems of Strength of the National Academy of Sciences of Ukraine under the direction of  Dr. V.V.Kharchenko, www.ipp.kiev.ua.

• Coordinate table with possibility to move precisely a tested specimen along two coordinates relatively the indenter;

• Replaceable precision load cells (HBM) for extension of load measurement range;

• Absolute displacement sensor for positioning of the loading rod and indenter;

• Two precision displacement sensors for measurement error  minimization of indentation depth;

• Super servo-drive for control of  indentation rate over a wide range;

• Control of the machine with the manual console or by software in fully automatic mode.

• Maximum test load - 10 kN;
• Load measurement range: from 0 up to 1 kN and from 0 up to 10 kN;
• Error of load measurements - no more 1 %;
•  Indentation range ± 2500 µm;
• Error of indentation measurement, max. - no more 0,5 %;
• Displacement rate of loading rod  - from 50 up to 50000 µm/min.
