Is it shear locking or mesh refinement problem?
Structural Engineering and Mechanics, 2014 Locking phenomenon is a mesh problem and can be staved off with mesh refinement. If the studier is not preferred going to the solution with increasing mesh size or the computer memory can stack over flow than using higher order plate finite element or ...

Simple tests as critical indicator of intra-ply shear locking
Key Engineering Materials, 2013 Standard finite elements can exhibit the numerical artifact of intra-plyshear locking during forming simulations. The displacement fields of elementsare piecewise continuous and cannot correctly capturediscontinuities in the shear field.

Development of shear locking-free shell elements using an enhanced assumed strain formulation [PDF]
International Journal for Numerical Methods in Engineering, 2002 The degenerated approach for shell elements of Ahmad and co-workers is revisited in this paper. To avoid transverse shear locking effects in four-node bilinear elements, an alternative formulation based on the enhanced assumed strain (EAS) method of Simo

Solutions to intra-ply shear locking in finite element analyses of fibre reinforced materials [PDF]
Composites Part A: Applied Science and Manufacturing, 2008 Intra-ply shear locking results in unrealistic fibre stresses and spurious wrinkling in composite forming simulations. Three remedies were investigated: aligning the mesh, applying reduced integration and using multi-field elements.

Conforming shear-locking-free four-node rectangular finite element of moderately thick plate
Journal of the Mechanical Behavior of Materials, 2016 An outline of the modified Mindlin plate theory, which deals with bending deflection as a single variable, is presented. Shear deflection and cross-section rotation angles are functions of bending deflection. A new four-node rectangular finite element of

Analyzing of thick plates with cutouts using the meshless (EFG) method based on higher order shear deformation theories for solving shear-locking issue [PDF]
Numerical Methods in Civil Engineering, 2021 Although the finite element method (FEM) is a well-established method for modelling the thick plates, in some cases FEM encounters some difficulties such as shear locking and decrease in the accuracy of results caused by stress concentration around the ...

Study of the Discrete Shear Gap Technique in Timoshenko Beam Elements
Civil Engineering Dimension, 2017 A major difficulty in formulating a finite element for shear-deformable beams, plates, and shells is the shear locking phenomenon. A recently proposed general technique to overcome this difficulty is the discrete shear gap (DSG) technique. In this study,
