   Abstract

The problem of interaction of a thin elastic infinite plate weakened by several holes with a system of superimposed patches is considered. Each patch covers completely one or several holes or is located in the exterior of all holes. Some holes may not be covered by patches. The patches are attached to the plate continuously along their boundaries. The patches and the holes can be of arbitrary shape and size. The plate is loaded with given in-plane stresses at infinity and along the boundaries of the holes. All parts of the construction are assumed to be in a generalised plane stressed state. Using special integral representations of complex potentials, the problem is reduced to a system of singular integral equations. Numerical examples on reinforcement of a plate with two or three holes covered by one or two patches are given.
