Evolution of tensile stress $\mathrm{\Sigma }$ and entropic tensile stress ${\mathrm{\Sigma }}_e(N_e)$ as a function of Hencky strain ${\epsilon }_H$ for $N=500$ and $k_{\mathrm{bend}}=1.5$ at Rouse Weissenberg number ${\mathrm{Wi}}_R=25$. The (orange) solid line and (green) dashed line represent the entropic stresses ${\mathrm{\Sigma }}_e(N_e)$ evaluated according to the Hookean spring law and Eq. (1) of Ref. [1], respectively. The inset shows the relative change bond bending potential $\mathrm{\Delta }=(⟨U_{\mathrm{bend}}{⟩}_0-⟨U_{\mathrm{bend}}{⟩}_{\text{steady}})/⟨U_{\mathrm{bend}}{⟩}_0$ in steady state as a function of ${\mathrm{Wi}}_R$.
