Electro-Thermal Mechanical Testing (ETMT)

The Electro-Thermal Mechanical Testing (ETMT) machine is an innovative testing system developed by NPL and supplied by Instron. Brief details:

  • ±3.5kN load capability
  • Resistance heating via direct current (DC) through the specimen
  • Temperature control/monitoring by an R-type thermocouple spot-welded to the centre of the gauge length
  • Static and cyclic testing conditions for both load and temperature parameters

The machine is capable of assessing a wide range of materials physical and mechanical properties on test-pieces of cross-sections as small as 1 mm x 1 mm. This is a very efficient, inexpensive, and quick testing method particularly when there are limitations in making full-scale specimens. This testing method also allows specimens to be extracted from actual components to assess location-specific properties. 

 

Typical mechanical testing such as tensile, compression, creep, low cycle fatigue (LCF), and thermo-mechanical fatigue (TMF) testing could be carried out on this machine. Example of test data generated:
