O. Polit et al., A NEW 8-NODE QUADRILATERAL SHEAR-BENDING PLATE FINITE-ELEMENT, International journal for numerical methods in engineering, 37(3), 1994, pp. 387-411
A new eight-node quadrilateral shear-bending Reissner-Mindlin plate fi
nite element for the very thin and thick plates without locking and sp
urious zero-energy modes is presented. The element has very good conve
rgence characteristics both for thin and thick plates, is hardly insen
sitive to mesh distortions, and passes the patch tests. The formulatio
n of the element is derived from a displacement variational principle
and some general criteria to compute inconsistent transverse shear str
ains. These criteria have been applied with success to four- and eight
-node quadrilateral plate finite elements and could be applied to cons
truct triangular elements. The eight-node quadrilateral shear-bending
plate finite element proposed has been found to be very efficient.
