BEHAVIOR OF RAIL HEAD METAL WHEN SUBJECTED TO FATIGUE

LE COMPORTEMENT A LA FATIGUE DU METAL DU CHAMPIGNON DES RAILS

Complete calculation of the cycles of stresses produced in the rail head by a wheel going over it is a way of establishing the influence of the various running parameters on the behavior of the rail head metal when subjected to fatigue. Such calculations were carried out by using a recently developed fatigue criterion valid for complex cycles. It is thus possible to attack the problem of establishing nonempirically the permissible load in relation to wheel diameter.
