Creep and Stress Rupture Testing


Creep and Stress rupture tests evaluate the ability of a part or material to safely hold a load, usually at in elevated temperature and sometimes humidity-specific environments.

Creep Testing measures the deformation of the material and the time it takes to rupture, Stress Rupture measures only the time it takes to rupture. These measurements are critical to manufacturers in a wide range of industries including aerospace and power generation, among others.

Creep and Stress Rupture Testing Capabilities

  • Creep samples are tested at temperatures up to 1500ºF
  • Stress rupture samples to 2100ºF
  • Controlled relative humidity from 40% to 70%.
  • Frames load capacity up to 12,000 lbs.
  • Specimens single-point machined 
  • Low-stress grind available
  • Full digital temperature and strain data logging
  • Fast, accurate, measurable results
