Planar elasticity problems are considered for thin domains fixed along a small part of the end region boundary. The analysis involves two small parameters: the normalized thickness of the body and the normalized length of the fixed part of the boundary. The aim of the paper is to derive an asymptotic approximation of the solution to a boundary-value problem in such a domain and, in particular, analyze the effective boundary conditions, which occur for the leading-order terms of the asymptotics. We include applications for problems of both anti-plane shear and plane strain elasticity.
