Polyharmonic Multiquadric Particular Solutions for Reissner/Mindlin Plate [PDF]
Analytical particular solutions of the polyharmonic multiquadrics are derived for both the Reissner and Mindlin thick-plate models in a unified formulation. In the derivation, the three coupled second-order partial differential equations are converted into a product operator of biharmonic and Helmholtz operators using the Hörmander operator ...

A DPG method for Reissner-Mindlin plates
We present a discontinuous Petrov-Galerkin (DPG) method with optimal test functions for the Reissner-Mindlin plate bending model. Our method is based on a variational formulation that utilizes a Helmholtz decomposition of the shear force. It produces approximations of the primitive variables and the bending moments.

A higher order triangular plate finite element using Airy functions
The present paper describes the formulation of a new moderately thick plate bending triangular finite element based on Mindlin–Reissner plate theory. It is called a Great Triangular Moderately Thick Plate Finite Element, or GTMTPFE.

Laminated Beam Analysis by Polynomial, rigonometric, Exponential and Zig-Zag Theories [PDF]
A number of refined beam theories are discussed in this paper. These theories were obtained by expanding the unknown displacement variables over the beam section axes by adopting Taylor's polynomials, trigonometric series, exponential, hyperbolic and zig ...

A numerical approach for modelling thin cracked plates with XFEM [PDF]
The modelization of bending plates with through the thickness cracks is investigated. We consider the Kirchhoff-Love plate model which is valid for very thin plates.

Higher‐Order, Mixed‐Hybrid Finite Elements for Kirchhoff–Love Shells
ABSTRACT A novel mixed‐hybrid method for Kirchhoff–Love shells is proposed that enables the use of classical, possibly higher‐order Lagrange elements in numerical analyses. In contrast to purely displacement‐based formulations that require higher continuity of shape functions as in isogeometric analysis (IGA), the mixed formulation features ...

Tension chord model for CFRP‐prestressed structural concrete
Abstract This paper introduces a mechanical model for steel‐reinforced concrete prestressed with bonded CFRP rods and presents the findings of an experimental campaign conducted to validate the model. The study is part of a project aiming at developing a railway bridge system in Switzerland that utilizes stainless steel reinforcing bars combined with ...
