摘要：

The orthotropic of a solid is characterized by the material directions ((1) over right arrow, (2) over right arrow, (3) over right arrow) and corresponds to six main directions of the crack' distribution 21, 31, 32, 12, 13 and 23 (the first number corresponds to the normal of the crack's plan, the second in the crack's front). In this work, it was suggested studying the crack's bifurcation solicited in the mixed mode of an anisotropic fracture's specimen by varying several geometrical parameters. The study showed that the critical angle of bifurcation depends on the crack's length, the specimen's height, the angle of load as well as on the chosen configuration.
