The boundary conditions of three-dimensional (3D) elastic bodies are clear physically and mathematically. In many engineering applications, a 3D analysis is numerically expensive, thus two-dimensional (2D) or one-dimensional (1D) analyses are preferred in practice. These 1D and/or 2D elastic bodies are constructed by applying prior assumptions based on intuition and/or physics. An approximation to the 3D elastic body is inevitable during the dimensional reduction, this affects both governing equation and boundary condition. The boundary conditions (BCs) of 1D and/or 2D elastic bodies are generally derived from variational principles. However the principle does not explicitly render how to prescribe the displacement boundary. In this paper, the BCs obtained by the variational principle are qualitatively assessed by comparing those obtained by the sophisticate decay analysis method. The asymptotic correctness of the BCs is discussed via the example of cantilever loaded at the end.
