Abstract. We show that the Reissner­Mindlin plate bending model has a wider range of applicability than
the Kirchhoff­Love model for the approximation of clamped linearly elastic plates. Under the assumption
that the body force density is constant in the transverse direction, the Reissner­Mindlin model solution
converges to the three-dimensional linear elasticity solution in the relative energy norm for the full range of
surface loads. However, for loads with a significant transverse shear effect, the Kirchhoff­Love model fails.

1. Introduction
The Kirchhoff­Love and Reissner­Mindlin models are the two most common dimensionally
reduced models of a thin linearly elastic plate. It is often remarked in the engineering
literature, based mostly on computational evidence, that the Reissner­Mindlin model is
more accurate, particularly for moderately thin plates and when transverse shear plays a
