Combining hierarchic high order and mixed-interpolated finite elements for Reissner-Mindlin plate problems (Q1892459)

Recently, numerical experiences with high order finite elements applied to the plain Reissner-Mindlin formulation have shown a consistent improvement in avoiding the locking problem. Meanwhile some mixed- interpolated finite elements have been suggested and shown to be locking free. In this paper we propose the combination of the two classes of elements introducing a family of hierarchic high order mixed-interpolated finite elements.
