What Is Low Cycle Fatigue Testing?
Low cycle fatigue testing (LCF) is defined as a fatigue process where the failures happen in roughly less than 10,000 cycles. The test is run in strain control and the load is a dependent variable. Application of Low Cycle Fatigue LCF is characterized by a high amplitude and low frequency deformation and plastic strains. Low cycle fatigue is generally applicable in industries where the materials are used in temperature cycling with varying load conditions including aerospace, automotive, oil and gas industries.
AdvanSES has the expertise to carryout Low cycle fatigue testing on components as well as material samples as per ISO and ASTM standards.
Fatigue testing at AdvanSES is carried out to study the following three stages of the low cycle fatigue process.
- The nucleation or formation of crack in the sample component or specimen.
- The propagation of the crack in the component/specimen
- The ultimate failure of the component/specimen. The failed specimen can be studied using microscopy and SEM techniques to provide more information on the weak links.
In engineering components Low cycle fatigue (LCF) tests are designed to replicate high-strain conditions that can develop in the region of a local discontinuity where fatigue damage is concentrated.
We have in-house machining capabilities to offer faster turn around times.
