RESEARCH ON OPTIMIZATION OF S.N.C.F. AXLES. PART II

Research by SNCF to enhance the reliability of axles has continued. This reports the results of investigations into mechanical surface treatment, particularly prestressing by shot peening. Fatigue strength can be increased 20 percent by shot peening, but this effect may be negated by corrosion.
