The pos.ibility of us.ng Neumann＇s.method to s.lve the boundary problems.for thin elas.ic s.ells.is.s.udied. The variational s.atement of the s.atic problems.for the s.ells.allows.for a problem examination within the dis.ribution s.ace. The convergence of Neumann＇s.method is.proven for the s.ells.with holes.when the boundary of the domain is.not completely fixed. The numerical implementation of Neumann＇s.method normally requires.s.gnificant time before any reliable res.lts.can be achieved. This.paper s.gges.s.a way to improve the convergence of the proces., and allows.for parallel computing and evaluation during the calculations.
