The optimal testing machine for demanding tests, also under alternating load

This patented electromechanical fatigue testing machine with backlash-free zero crossing features a central lead screw and is ideal for force and strain controlled creep fatigue tests. The Kappa SS-CF provides extremely high flexibility, covers the complete range of creep testing applications and is ideal for a wide range of tests with alternating load at both ambient and high-temperature conditions.

• Force and strain controlled creep fatigue tests with alternating load (through zero)
  e.g. CF, LCF, CFCG and TMF
• Advanced creep tests
  - Fatigue tests with threshold and alternating load
  - Strain modeling (e.g. determination of creep curve at different loads)
  - Creep ductility
  - Creep test with slow strain rates (SSRT)
  - Creep data from components tests
• Static and cyclic crack growth/widening test
• Determination of hydrogen embrittlement
• Tests with stepless force and temperature adjustment
• Relaxation tests
• Creep test up to break
  - Creep rupture
  - Stress rupture
• Classic creep tests
• Short-term tensile, compression and flexure tests can also be performed with this testing machine

Specific machine design

• Specially designed and patented for fatigue tests
• Optimal for force and strain controlled creep fatigue tests with alternating load, e.g. CF, LCF, CFCG and TMF
• Load frame with backlash-free central lead screw drive and precision guidance via four steel columns for precise axial loading
• High drive control frequency of 1000 Hz. This allows for precise force and strain control for a wide range of applications.
• High-resolution force and travel measurement for optimum control properties, especially at very low test speeds
• Precise loading rate with tolerance of ± 0.1 % of the set speed in the measurement range of 1 μm/h to nominal speed, unloaded or under constant load
• Precision testing machine to DIN EN ISO 7500-1
