EFFECT OF THE DEVELOPMENT OF RESIDUAL STRESSES IN SOLID WHEELS ON WEAR

EVOLUTION DES CONTRAINTES RESIDUELLES DANS LES ROUES MONOBLOCS. INFLUENCE SUR LES DEGRADATIONS

After describing the special procedures employed to determine the residual stresses by destructive methods and X-ray diffraction, an assessment is made of the results obtained witn new solid wheels, to which different braking powers had been applied, over varied distances. The effect of these stresses is studied on the following mechanisms of wear: thermal flaws, fatigue cracks in the rim or the center and buckling.
