Abstract (en)

Equilibrium of deformable body on localy deformable ground surface is considered. To express the potential of the ground stress field, their rigidity matrix in integral form is used. Initial deformations are also estimated as well as initial displacements of the ground. The obtained equational system for the systems on deformable ground is expressed by displacements and stress fields. Not only the deformable ground of the body surface is estimated by boundary conditions but the field of initial deformations as well. The general functionals (Lagrange, Colonnetti, Haar-Karman, Castigliano) of calculation theory for the systems on deformable body are presented. Extreme properties of these functionals are considered as well.
