摘要: This paper is concerned with the computation of 3D vertex singularities anisotropic elastic elds Dirichlet boundary conditions, focusing on derivation error estimates for a nite element method graded meshes. The are described by eigenpairs corresponding operator pencil spherical polygonal domains. main idea to introduce modied quadratic variational eigenvalue problem which consists two self-adjoint, positive denite sesquilinear forms and skew-Hermitean form. discretized Based regularity results eigensolutions derived both eigenvalues eigensolutions. Finally, some numerical presented.
