The reformulation of Brezzi and Fortin is employed to prevent locking. Taking advantage of the least squares approach, we use only continuous finite elements for all the unknowns. In particular, we may use continuous linear finite elements. The difficulty of satisfying the inf-sup condition is overcome by the introduction of a stabilization term into the least squares bilinear form, which is very cheap computationally. It is proved that the error of the discrete solution is optimal with respect to regularity and uniform with respect to the parameter\n                    <inline-formula content-type=\"math\/mathml\">\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" alttext=\"t\">\n                        <mml:semantics>\n                          <mml:mi>t<\/mml:mi>\n                          <mml:annotation encoding=\"application\/x-tex\">t<\/mml:annotation>\n                        <\/mml:semantics>\n                      <\/mml:math>\n                    <\/inline-formula>\n                    . Apart from the simplicity of the elements, the stability theorem gives a natural block diagonal preconditioner of the resulting least squares system. For each diagonal block, one only needs a preconditioner for a second order elliptic problem.\n                  <\/p>","DOI":"10.1090\/s0025-5718-98-00972-7","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T18:14:28Z","timestamp":1027707268000},"page":"901-916","source":"Crossref","is-referenced-by-count":28,"title":["A negative-norm least squares method for Reissner-Mindlin plates"],"prefix":"10.1090","volume":"67","author":[{"given":"James","family":"Bramble","sequence":"first","affiliation":[]},{"given":"Tong","family":"Sun","sequence":"additional","affiliation":[]}],"member":"14","published-online":{"date-parts":[[1998]]},"reference":[{"issue":"6","key":"1","doi-asserted-by":"publisher","first-page":"1276","DOI":"10.1137\/0726074","article-title":"A uniformly accurate finite element method for the Reissner-Mindlin plate","volume":"26","author":"Arnold, Douglas N.","year":"1989","journal-title":"SIAM J.
