5. Glossary

homogeneous property

A physical property whose value does not depend on the coordinates of the point M(x,y,z) at which it is determined. Otherwise, the property is said to be inhomogeneous.

isotropic property; propriété isotrope

A physical property whose value does not depend on the direction vector (u, v, w) of the direction in which it is determined. Otherwise, the property is said to be anisotropic.

reuss mean value of elastic compliances; moyenne de Reuss des compliances élastiques

Average determined according to the Reusss model, which assumes that the local stress in the polycrystal is homogeneous and equal to the average value. This scheme is well suited to microstructures with grains elongated in the direction perpendicular to the tensile direction (serial...
