Locking problem and variable reducing procedure in Trefftz method
ACTA MECHANICA SOLIDA SINICA(2000)
Abstract
The Trefftz-type boundary solution methods([1]) are applied in analysing moderately thick plate bending problems. A new type of locking problem caused by the overflow of Trefftz functions has been found and a so-called variable-reducing procedure for eliminating such a phenomenon is also proposed.
