Tensile Creep Strain and Activation Energy.

reportActive / Technical Report | Accession Number: ADA283264 | Open PDF

Abstract:

In a set of PMMA creep curves, at several temperatures under the same dead load, any constant tensile creep strain e will intercept a set of time- temperature points. In PMMA we can relate such a set of time-temperature points to an equivalent set of relaxation time-temperature points associated with a constant activation energy delta H obtained with the Axrhenius equation. Then delta H is proportional to e over their common intercepted set of time- temperature points. Tensile creep, Activation energy, Arrhenius equation, PMMA
