【 摘 要 】

The article is devoted to the mathematical model of bending of machines and constructions. The fact that they are made of multimodulus materials is taken into consideration. The priority is given to the multilayer qualities of such materials. The peculiarity of their deformation under real conditions due to the reciprocal slip of layers is taken into account. The redistribution of forces between the layers is achieved through the variable joint rigidity which is also represented in the given article. The construction of the mathematical model is given in details. The calculation method of bending of composite plates with layers of material with strength differential effect is described. While calculating the stress-strained state, the influence of rigidity of the multilayer bonding was taken into consideration.
