Strength Laboratory performs wide range of standard tests (according to PN, EN or ASTM). Among the standard testing techniques applied in the laboratory most important are:

  • Static tension or compression tests (also thin plates compression using special, designed in IFTR fixture) in the range of temperatures from -100° C to 300° C,
  • High and Low Cycle Fatigue tests in the range of temperatures from -100° C to 300° C,
  • Fracture Toughness (KIC, JIC, CTOD) tests in the range from -100° C to 300° C,
  • Fatigue Crack Growth Rate testing in the range of temperatures from -100° C to 300° C,
  • Creep testing in temperatures up to 1200° C,
  • Impact testing,
  • Measurements of residual stresses by the hole-drilling strain gage method.
A  non-standard, unique testing techniques were also developed here as the result of the co-operation of IFTR with industrial partners and other research units. Standard tests are performed in uniaxial stress state (simple tension or compression). Most of them (excluding fracture toughness tests) were elaborated to be performed on tubular or cruciform specimens in the complex stress state. The most important non-standard  testing techniques are:
  • Static and quasi-dynamic loading along the proportional and non-proportional load paths in stress space. Those complex stress tests are performed in the temperatures from -100° C to 300° C.
  • Complex stress state Low and High Cycle Fatigue tests in the temperatures from -100° C to 300° C.
  • Complex stress state creep tests in the temperatures up to 1200° C.
  • High strain-rate (up to 104 1/s) testing of the materials.
