L'équation de Hollomon est une relation empirique de loi de puissance qui décrit la partie de la vraie contrainte-vraie souche curve between the onset of plastic deformation (yielding) and the onset of necking (UTS). The equation is [latex]sigma_t = K epsilon_t^n[/latex], where [latex]sigma_t[/latex] is the true stresser, [latex]epsilon_t[/latex] is the true plastic strain, K is the strength coefficient, and n is the strain-hardening exponent.
