Creep tests, i.e. the process of slow increase of deformations of the material subjected to long-term constant load, are an important source of information in the assessment of material durability. They are performed on creep-testing machines in which the uniaxial strain of the sample is gravitationally obtained by means of calibrated weights hung on the arm of the creep-testing machine.

Creep tests – testing capabilities

Our equipment includes 36 test stations – creep-testing machines, enabling three types of tests:

• • with deformation registration,
  • with time to break registration,
  • cyclic tests (LCF Long Dwell) on 14 stands using lifts.

The deformation of the samples is recorded using high-temperature extensometers. We supervise and record the test using a computer system in real time. 

Our laboratory, due to the long duration of testing, is equipped with a UPS voltage maintenance system and air-conditioned rooms with temperature and air humidity recording.
