Definition

EN

scalar (ISO 80000-2: Mathematics) quantity describing surface action of a force into a body equal to:

σ n = d F n d A

where F n is the normal component of force (force) and

A is the area (ISO 80000-3: Space and time) of the surface element

FR

grandeur scalaire décrivant l'action surfacique exercée par une force sur un corps, égale à :

σ n = d F n d A

où F n est la composante normale de la force (force) et A est l'aire (ISO 80000-3: Space and time) de l'élément de surface

Notes

EN

A couple of mutually opposite forces of magnitude F acting on the opposite surfaces of a slice (layer) of homogenous solid matter normal to it, and evenly distributed, cause a constant normal stress σ n = F A in the slice (layer).

FR

Un couple de forces mutuellement opposées de norme F s'exerçant sur les surfaces opposées d'une tranche (couche) d'une matière solide homogène, normales à celle-ci et réparties uniformément, provoque une contrainte normale constante σ n = F A dans la tranche (couche).
