Low Cycle Fatigue Testing (LCF)

In low cycle fatigue testing (LCF),the test is normally run in strain control with the load as a dependent variable.The strain variables that are usually defined by the customer are testing temperature,wave type,frequency (and hold time for a trapezoidal wave),mean strain,strain amplitude,and discontinue cycles.LCF tests are often performed at elevated temperatures.Loading Rates and Tensile Properties / Fracture Toughness Up to a strain rate of about 1s -1 only a small to moderate increase in yield strength of about 70MPa for this steel type is obtained.The strain rate sensitivity increases beyond 1s -1,up to a value of about 10 3 s -1.(Data in Fig.5 were up to this strain rate values only.) Beyond 10 3 s -1 the sensitivity to strain rate becomes extreme.Loading Rates and Tensile Properties / Fracture Toughness Up to a strain rate of about 1s -1 only a small to moderate increase in yield strength of about 70MPa for this steel type is obtained.The strain rate sensitivity increases beyond 1s -1,up to a value of about 10 3 s -1.(Data in Fig.5 were up to this strain rate values only.)
