Locking-free finite elements for the Reissner-Mindlin plate [PDF]
Mathematics of Computation, 1999 Summary: We analyze two new families of Reissner-Mindlin triangular finite elements. One family, generalizing an element proposed by \textit{O. C. Zienkiewicz} and \textit{D. Lefebvre} [Int. J. Numer. Methods Eng. 26, No. 5, 1169-1184 (1988; Zbl 0634.73064)] approximates (for \(k\geq 1)\) the transverse displacement by continuous piecewise polynomials ...

Structural Concrete, Volume 26, Issue 4, Page 4365-4388, August 2025.Abstract The current codes and standards for the design of anchorages against concrete cone breakout failure require the base plate to be rigid such that each anchor is subjected to almost equal load under concentric tension, and there is a linear distribution of anchor forces for groups under eccentric tension or bending.

Three-dimensional flat shell-to-shell coupling: numerical challenges
Curved and Layered Structures, 2017 The node-to-surface formulation is widely used in contact simulations with finite elements because it is relatively easy to implement using different types of element discretizations.

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.The academic community has paid much attention to the research topic of structural health monitoring (SHM) and damage identification for several decades, which flourishes the development of diverse damage identification approaches. The sensitivity‐based damage identification enjoys popularity due to its clear physical meaning and long development ...

An asymptotic strain gradient Reissner-Mindlin plate model [PDF]
, 2013 In this paper we derive a strain gradient plate model from the three-dimensional equations of strain gradient linearized elasticity. The deduction is based on the asymptotic analysis with respect of a small real parameter being the thickness of the ...

Curved Three‐Director Cosserat Shells with Strong Coupling
Computer Graphics Forum, Volume 43, Issue 8, December 2024.Abstract Continuum‐based shell models are an established approach for the simulation of thin deformables in computer graphics. However, existing research in physically‐based animation is mostly focused on shear‐rigid Kirchhoff‐Love shells. In this work we explore three‐director Cosserat (micropolar) shells which introduce additional rotational degrees ...

A locking-free quadratic nurbs-based isogeometric formulation for plates analysis
Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2012 A new Reissner-Mindlin plate formulation based on a quadratic NURBS-based isogeometric is presented. In order to avoid the transverse shear locking and to improve the accuracy of the present formulation, the quadratic NURBS-based isogeometric is ...
