agree  Schtroumpf: Ca, c'est Wechselbeanspruchung. Le 2e et 3e terme méritent qu'on précise "due aux dilatations" ou qqc du genre. "Due aux contraintes thermiques" serait encore mieux, mais il faut être sûr que c'est bien ça !

agree  Giselle Chaumien: avec Wiebke pour le début de sa remarque. Mais il ne s'agit pas à priori de dilatation thermique. On peut provoquer une Dehnung en tirant sur un élastique par exemple.
