Abstract

The model for drying creep from Part III is here extended for the temperature effect. The basic, additive form of the double power law and the shrinkage-like term are preserved, but certain coefficients become temperature-dependent to reflect the acceleration of drying and of aging. Satisfactory agreement with test data is achieved.

Résumé

On applique ici à l'influence de la température le modèle de fluage décrit dans la troisième partie. On conserve la forme de base qui est celle d'une forme additive de la loi de double puissance et du terme qui correspondrait au fluage, mais certains coefficients deviennent dépendants de la température afin de traduire l'accélération du séchage et du vieillissement. On obtient une bonne concordance avec les résultats d'essai.
