Adaptive mesh refinements for thin shells whose middle surface is not exactly known [PDF]
, 2008 A strategy concerning mesh refinements for thin shells computation is presented. The geometry of the shell is given only by the reduced information consisting in nodes and normals on its middle surface corresponding to a coarse mesh.

Evaluating the exit pressure method for measurements of normal stress difference at high shear rates [PDF]
, 2020 A challenge for polymer rheology is the reliable determination of shear dependent first normal stress difference (N-1 values) at high shear rates (>10 s(-1)).

Bending solution of high-order refined shear deformation theory for rectangular composite plates [PDF]
International Journal of Solids and Structures, 1994 Abstract A new high-order refined shear deformation theory based on Reissner's mixed variational principle in conjunction with the state-space concept is used to determine the deflections and stresses for rectangular cross-ply composite plates. A zig-zag shaped function and Legendre polynomials are introduced to approximate the in-plane displacement ...

Bending of functionally graded plates via a refined quasi-3D shear and normal deformation theory
Curved and Layered Structures, 2018 Bending of functionally graded plate with two reverse simply supported edges is studied based upon a refined quasi three-dimensional (quasi-3D) shear and normal deformation theory using a third-order shape function.

A family of higher-order single layer plate models meeting $C^0_z$ -- requirements for arbitrary laminates [PDF]
, 2019 In the framework of displacement-based equivalent single layer (ESL) plate theories for laminates, this paper presents a generic and automatic method to extend a basis higher-order shear deformation theory (polynomial, trigonometric, hyperbolic, ...) to ...

Free vibration of axially loaded rectangular composite beams using refined shear deformation theory [PDF]
Composite Structures, 2012 Free vibration of axially loaded rectangular composite beams with arbitrary lay-ups using refined shear deformation theory is presented. It accounts for the parabolical variation of shear strains through the depth of beam. Three governing equations of motion are derived from the Hamilton’s principle.

Buckling Response of Functionally Graded Porous Plates Due to a Quasi-3D Refined Theory
Mathematics, 2022 A quasi-3D refined theory is used to investigate the buckling response of functionally graded (FG) porous plates. The present theory takes into consideration the effect of thickness stretching. Three models of FG porous plates are presented: an isotropic
