New additional conditions required for the uniqueness of the 2D elastostatic problems formulated in terms of potential functions for the derived Papkovich-Neuber representations, gruvi golden lager are studied.Two cases are considered, each of them formulated by the scalar potential function plus one of the rectangular non-zero components of the vector potential function.For these formulations, in addition to the original (physical) boundary conditions, two new additional conditions are required.In addition, for the complete Papkovich-Neuber formulation, expressed by the scalar potential plus two components of the vector potential, the additional conditions established previously for the three-dimensional case in z-convex domain can be applied.
To show the usefulness of these new conditions in a numerical scheme two applications are numerically solved by the network method for the three cases of metabo 15-gauge finish nailer cordless potential formulations.
