Investigation into the growth mechanism of shelly cracks and a method of prevention is reported. Examinations included track condition, materials quality, loading condition and friction and wearing phenomenon of affected rails. It was found that in the ordinary contact condition, the contact stress between tyre and rail is so large that plastic flow is caused. With the progress of plastic deformation, steel becomes hard and its elastic limit rises. After these changes, rail surface becomes fit… CONTINUE READING
