Rib-Reinforced Ultralight and Ultra-Strong Shell Lattices. [PDF]
Adv Sci (Weinh)This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Imperfection-Enabled Strengthening of Ultra-Lightweight Lattice Materials. [PDF]
Adv Sci (Weinh)This study identifies different compressive failure modes of cubic lattices with different relative densities and proposes a novel imperfection‐enabled strengthening mechanism of ultra‐lightweight lattice materials. Geometric imperfections are proven to be advantageous in enhancing the stability and strength of lattice materials at ultra‐low relative ...

A volume-averaged nodal projection method for the Reissner-Mindlin plate model [PDF]
, 2018 We introduce a novel meshfree Galerkin method for the solution of Reissner-Mindlin plate problems that is written in terms of the primitive variables only (i.e., rotations and transverse displacement) and is devoid of shear-locking. The proposed approach

Meshless Modelling of Laminate Mindlin Plates under Dynamic Loads
Communications, 2012 Collocation method and Galerkin method have been dominant in the existing meshless methods. A meshless local Petrov-Galerkin (MLPG) method is applied to solve laminate plate problems described by the Reissner-Mindlin theory for transient dynamic loads ...

International Journal for Computational Civil and Structural Engineering, 2021 This paper proposes a method for creating finite elements with simultaneous approximation of functions corresponding to displacements and rotations. New triangular and quadrangular finite elements have been created, which can have additional nodes on the

On boundary layer in the Mindlin plate model: Levy plates [PDF]
, 2008 This work is related to the bending problem of thick rectangular Levy plates. Series solution for the Mindlin (thick) plate model is obtained and represented as a sum of the Kirchhoff (thin) plate model solution, the ``shear terms'' and the ``boundary ...

Model adaptivity for finite element analysis of thin or thick plates based on equilibrated boundary stress resultants [PDF]
, 2009 Purpose – The purpose of this paper is to address error-controlled adaptive finite element (FE) method for thin and thick plates. A procedure is presented for determining the most suitable plate model (among available hierarchical plate models) for each ...
