Williams-Landel-Ferry-Gleichung

Die Williams-Landel-Ferry-Gleichung (nach Malcolm L. Williams, Robert F. Landel und John D. Ferry) beschreibt die Temperaturabhängigkeit von Relaxationsmechanismen bei amorphen Polymeren und anderen Werkstoffen.

\log _{10}(a_{T})=-8{,}86\,{\frac {T-T_{\mathrm {s} }}{101{,}6\,\mathrm {K} +T-T_{\mathrm {s} }}}
