In this paper the differential equation of the cracked plate, using the classical variational method of Lagrange is worked out. The displacements equation of Lame with the boundary conditions and compatibility conditions in the crack is obtained. The total differential equation in the class of the two-dimensional general vector functions is shown. In this model the effect of discontinuity displacement vector into account is taken.
