✦ Synopsis

The angle of propagation 6, for a crack in mixed mode fracture, predicted according to the new criteria maxu,, maxlr,,J and maxu,, presents an improved fit to the experimental data, when the influence of the constant term (in the expansion of stresses in series of r) is taken into account.

The variation of the direction or, of crack propagation in mixed mode with the angle j? of the inclined crack is shown to fit very well to the variation of @, of the bisector of the angle of directions S,, and ff,, of max o, and sufficiently well to that of @,, bisector of the angle of directions &
