Metal tests in conditions of controlled strain energy density
A new concept of the determination of fatigue properties was presented in the paper. Experimental procedures based on strain-life fatigue tests were developed. The total strain energy density parameter calculated during a loading cycle was applied as the control signal for fatigue testing of the specimens. The developed procedure extends the range of fatigue testing methods in the low-cycle fatigue, which should bring a new quality in the case of its use in fatigue life calculations.
