Vickers = 1,854 x F / d2

epsilon = deltaL / lo
teta = F / S
E = teta / epsilon
deltaL = Lf - Lo 
Lf = F/SE)*Lo +Lo
S = pi * r2 ou pi * d2) / 4
diametre = 2racine de (F/pi * teta) / 
W = 1/2 * Re0,2 * epsilon
V = Longueur * S
Wvolume = W/V
Z = (diametrefinal2 - diametre zero2)/diametre zero


W = l'énergie
V = volume
epsilon =  allongement (pourcentage d'allongement)
teta = force appliquée (contrainte) (MPa)
deltaL = variation de la longueur (mm) 
Lo = longueur de base (mm)
E = module d'élasticité (MPa)
F = newton
S = mm2
Lf = mm
