French term or phrase: RESSAUT
Immediate context:
PLIAGE MÉTAL / FONCTIONNEMENT
Le flan est plié entre un poinçon et une matrice. Différentes formes de profils (en U, en V…) sont possibles. Cependant les longueurs de plis sont limitées par la taille des machines et on ne peut jamais obtenir d’arêtes vives. En général, le rayon de courbure intérieur Ri suit la règle suivante :
e < Ri < 3 e où e est l’épaisseur du flan.

La maîtrise de l'élasticité de la matière peut s'avérer complexe. En effet, la déformation exercée est une déformation plastique et on assiste souvent à un phénomène de retour de la matière après le pliage, on parle de **ressaut** (environ 3°)


Is this spring/recoil or something along these lines? Does anyone know the accepted term in UK English?

spring-back
Explanation:
Even if my dictionary gives the French as "retrait élastique".

The amount by which a work piece after deformation reverts towards its original shape after removal of the forming load
Déformation élastique d'une pièce en sens inverse du formage qu'elle vient de subir, lorsque cesse l'application de l'effort de formage
[Dict. of Production Engineering, VoL 3, Sheet Metal Forming, CIRP]

The accompanying diagram shows a piece of sheet metal that has been bent from flat (180°) to form an angle alpha to itself and that has sprung back such that the final angle is alpha plus beta, where beta, in the diagram (not necessarily representative) is about one eighth of alpha.
