sure is set on the shores of the crack. Such a theoretical model reflects to some extent a mechanism of destruction of engineering structures with cracks when the water contained in them freezes to ice. The pressure on the shores of the crack created in this way may cause the growth of the crack. Therefore, such studies are important for estimating the strength in terms of the mechanics of destruction. In particular, in the case of piecewise homogeneous bodies with a crack, it is possible to reduce stress intensity coefficients through appropriate selection of mechanical characteristics of the composite components. 2. Literature review and problem statement Research into elastic state in the welded dissimilar halfplanes with cracks is addressed in a number of publications. In particular, a crack was studied, located in parallel to the lines of junction of dissimilar half-planes when stretching stresses are assigned on the infinity of the formed plane [1]. Termo
