Determination of destruction conditions by separation and shear when cutting the soils and primings with a wedge

This work is devoted to the development of the mathematical model of the fracture process when cutting the soils and primings with a dihedral wedge from the point of view of linear fracture mechanics. A stress-strained state at the apex of the leading crack is determined, as well as the conditions under which the soil layer will be destroyed by normal separation and transverse shear.
