    Abstract

    It is known that finite elements try to capture stresses within each discretized local region in a 'best-fit' sense. In the paper we examine the performance of a beam element based on a higher-order shear deformation theory and show that the best-fit paradigm accounts for the manner in which through-thethickness displacement and stresses are modelled. An a priori prediction derived from the paradigm is confirmed by a carefully chosen numerical experiment. This provides a measure of the quality of approximation as well as another 'falsification' of the best-fit paradigm.
