Analytical Formulation of Hybrid-Trefftz Thick Plate Elements
This paper discusses a domain-based formulation for hybrid-Trefftz thick plate elements. The formulation can be applied to triangular and quadrilateral elements, and enables an analytical formulation of these elements to be used. Techniques for improving the computational efficiency are explored, and a simple and accurate triangular element is formulated in this manner.
متن کاملHybrid Trefftz finite-element approach for plate bending on an elastic foundation
This paper presents a modified variational principle for the treatment of thin plate bending on an elastic foundation. The foundation may be of the Winkler or Pasternak type. A hybrid Trefftz (HT) finite-element (FE) model has been developed based on the principle and a new set of T-complete functions. The derivation of the new set of trial functions is based mainly on the resolution approach o...
متن کاملMixed Rectangular Finite Elements for Plate Bending
The paper describes three different rectangular plate bending elements based on Reissner's type stationary variational principles. They differ in the number of dependent variables approximated independently and also in the number of nodes per element. The first element types treats the transverse deflection and the three moments as unknowns at each of the corner nodes; the second element type t...
متن کاملQuadrilateral folded plate structure elements of reduced Trefftz type
General strategy for developing finite elements of general geometric shape explained on quadrilateral folded plate structure element ensuring invariance properties is presented in this paper. The basic idea of this strategy consists in using the natural coordinate system only for defining the element geometry and performing the element integration in a mapped biunit square. For defining the app...
متن کاملThe Mitc7 and Mitc9 Plate Bending Elements
We present in this paper two plate bending elements that have been proposed and mathematically analyzed previousIy by Bathe, Brezzi and Fortin: the MITC7 (a triangular) element and the MITC9 (a quad~late~l) element. The formation of these elements is summarized and example solutions are given that demonstrate the high accuracy of these elements. 1. lNTRODUCHON Although much research effort has ...
