heal.abstract	The behavior of the two main types of flows encountered in materials such as rocks, i.e., cracks and slits, under compressive and shear stresses has been examined. It was shown that the existence of a gap between the edges of a slit is allowing the inward movement, causing the development of a negative KI-SIF at its cornered extremities. On the other hand, for a slant ideal crack additional compressive stresses should develop because of the noncongruent deformation of its lips thus opposing the incompatible interpenetration of the crack flanks and causing an opening KI-SIF. Finally, for an ideal crack normal to the global stresses in the plate the cracked body behaves as a continuum without any singularity. In order to verify the validity of the above arguments the method of caustics has been used. After developing the appropriate equations of the caustics a series of experiments were executed giving results which support the already developed theory. © 1990 Springer-Verlag.	en
