Abstract
In this paper we consider homogeneous Dirichlet problem for the Lamé system with singularity caused by the reentrant corner to the boundary of the two-dimensional domain. For this problem we define the solution as a R ν -generalized one; we state its existence and uniqueness in the weighted set \(\mathring{\mathbf{W}}_{2,\nu }^{1}(\varOmega,\delta )\). On the basis of the R ν -generalized solution we construct weighted finite element method. We prove that the approximate solution converges to the exact one with the rate O(h) in the norm of W 2, ν 1(Ω), and results of numerical experiments are presented.
