Analysis of kinematic linked interpolation methods for Reissner-Mindlin plate problems

The approximation to the solution of Reissner-Mindlin plate problem is considered in the framework of finite element techniques. A general strategy, involving a linking operator between rotations and vertical displacements, is analyzed. An abstract convergence result is provided. Examples of elements falling into this framework are presented and shown to be stable and locking-free. Numerical tests detail the performances of the elements. EMAIL:: lovadina@ing.unitn.it
