CONSIDERATION OF THE EIGEN WEIGHT IN ANALYSIS OF DEFOR- MATION OF A PLATE WITH A WEAKENING
A phenomenological model of deformation is considered. It allows one to account for discrepancies in the displacements of the boundary of the hole, observable in the praxis. The suggested theory takes into account that the action of the material above the hole coincides with the direction of tensile stresses from an addi- tional problem; under the hole these directions are different. We come to the necessity to solve inverse problems. Without the consideration of the inverse problems, the computation of the stress state in such plates can not be considered as a correct one. Here, a basic additional condition is given by experimental measurements of displacements over and under the hole.
