Testing Capabilities

 

The HTF offers rigs capable of testing materials at temperatures up to 1000°C and with temperature cycling in a range of novel, demanding environments (pressurised gas for VHTR/HTR, liquid metal for SFR/LFR, inert atmospheres). 

 

The testing offered by the HTF includes,

but is not limited to:

 

  • Tensile Testing (loads up to 100 kN in tension and compression)

  • Fracture Testing (loads up to 250 kN and in the temperature range -196 to 1000°C)

  • Creep strain / rupture (loads up to 30 kN)

  • Creep crack growth (loads up to 30 kN)

  • Strain and load-controlled low cycle fatigue initiation
    (loads up to 100 kN in tension and compression)

  • Fatigue crack growth (loads up to 100 kN in tension
    and compression)

  • Creep-fatigue initiation / growth (loads up to 100 kN
    in tension and compression)

  • Thermo-mechanical fatigue initiation / growth
    (loads up to 100 kN in tension and compression)

  • Miniaturised tensile / creep / fatigue testing
    (loads up to 10 kN)

  • High cycle fatigue endurance / crack growth
    (up to 100 Hz test frequency and loads up to 10 kN)

 

To enable detailed analysis of tests the rigs can be equipped with the following analytical instrumentation:

  • Digital image correlation (DIC) for full field strain measurement (especially useful where welds are present)

  • Acoustic emission monitoring equipment for monitoring crack initiation and propagation

  • Potential difference monitoring equipment for monitoring crack initiation and crack growth
