1. In elastic theory, a sphere under homogeneous strain is transformed into an ellipsoid with this property: the ratio of the length of a line, which has a given direction in the strained state, to the length of the corresponding line in the unstrained state, is proportional to the central radius vector of the surface drawn in the given direction. 2.

La notion d’ellipsoïde de déformation a été conçue et utilisée par les ingénieurs pour l'étude de la déformation élastique, mais elle est utile également dans l'analyse des phénomènes de rupture. Une façon commode de se représenter la déformation consiste à imaginer une sphère soumise à une contrainte. Dans le cas le plus général cette sphère se déforme en un ellipsoïde à trois axes inégaux; mutuellement perpendiculaires. 1, record 8, French, - ellipso%C3%AFde%20de%20d%C3%A9formation

Il peut arriver que, dans un certain volume, la déformation soit la même en tous les points, c'est-à-dire que de petites sphères élémentaires sont transformées en ellipsoïdes semblables et semblablement orientés. Une sphère de dimensions finies est alors transformée également en un ellipsoïde semblable. La déformation est alors dite homogène.(...)

According to one [hypothesis], which is essentially Becker's, the directions of the joints were probably at an angle of 45 ° to the principal pressures, following the "glide planes" of the ellipsoid of deformation. But when such a rupture appears in a rock, it is immediately followed by a displacement of its margins. However, there are joints in undeformed rocks, and, in general, no slip takes place along the joints (...) 1, record 10, English, - Becker%27s%20hypothesis

Selon [l'hypothèse de Becker], les directions des diaclases seraient à 45 ° des pressions principales, suivant les "plans de glissement" de l'ellipsoïde de déformation. Mais, lorsqu'une telle rupture apparaît dans une roche, elle est immédiatement suivie d’un déplacement de ses lèvres. Or il peut y avoir des diaclases sans déformation de la roche, et en général aucun glissement ne se produit le long des diaclases(...) 2, record 10, French, - hypoth%C3%A8se%20de%20Becker
