Contact Interaction between an Infinite or Finite Stringer and Elastic Semi-Infinite Plate with a Finite Vertical Crack Coming out to the Stringer by One End

Problems on contact interaction between continuous or discontinuous infinite stringer or with a stringer of finite length with an elastic semi-infinite plate, having a finite crack, which vertically comes out to the lower bound of the stringer, are considered. The edges of the crack are loaded by vertical to them symmetric forces, and the upper bounds of the stringers are loaded by symmetrically distributed tangential forces.
