Experimental and analytical fatigue data for notched shafts in bending
An experimental investigation has been carried out on two types of shaft with different stress concentration features in order to determine the notched members fatigue life in bending. The shafts are made from steel with DIN specification CK45, which is widely used for machinery components. These...

| Summary: | An experimental investigation has been carried out on two types of shaft with
different stress concentration features in order to determine the notched members
fatigue life in bending. The shafts are made from steel with DIN specification CK45,
which is widely used for machinery components. These lives are compared with
estimates using the simple notch-stress-strain- conversion rules (e.g., Neuber; Linear)
and the strain energy density methods in conjunction with the Coffin-Manson strainlife
relationship. The paper demonstrates the simplicity and accuracy of the approach
although the predictive capability was found to depend on the magnitude of the elastic
stress concentration factor |
