Postbuckling analysis of thin plates by a hybrid Trefftz finite element method
A hybrid Trefftz finite element (HT FE) model fl~r postbuckling analysis of thin plates is presented, based on a modified variational principle. With the aid of incremental form of equilibrium equations, all non-linear terms may be viewed as pseudo-loads, and then the in-plane and out-of-plane equations can be unoccupied. As a consequence, the solution procedure for the postbuekling plate becom...
متن کاملTrefftz finite element method and its special purpose elements
Abstract In this report, the hybrid Trefftz finite element method based on nonsingular T-complete functions is first briefly reviewed for the purpose of establishing notation; then various special purpose elements are developed to illustrat the major advantage of Trefftz methods. In HT-FEM, elements containing local defects are treated by simply replacing the regular T-complete functions with a...
متن کاملMixed finite element formulation enriched by Adomian method for vibration analysis of horizontally curved beams
Abstract: The vibration analysis of horizontally curved beams is generally led to higher order shape functions using direct finite element method, resulting in more time-consuming computation process. In this paper, the weak-form mixed finite element method was used to reduce the order of shape functions. The shape functions were first considered linear which did not provide adequate accuracy....
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 کاملA Hybrid Finite Element Method for Stokes Flow: Part I-formulation and Numerical Studies
A hybrid finite element scheme, based on assumed deviatoric fluid stresses in the element and continuous velocity fields at the element-boundaries, is presented. The deviatoric stress and hydrostatic pressure field are subject a priori to the constraints of balance of momenta. the advantages of the present scheme are discussed, and its versatility is demonstrated through a few numerical example...
