The TDNNS method for Reissner-Mindlin plates [PDF]

open access: yes, 2017
A new family of locking-free finite elements for shear deformable Reissner-Mindlin plates is presented. The elements are based on the "tangential-displacement normal-normal-stress" formulation of elasticity.

Contact effects in bending affecting stress and formability [PDF]

open access: yes, 2010
If a strip is pulled over a curved tool there is a contact stress acting on the strip. This contact stress changes the stress state in the material, which is analysed with a simple model.

Bending-damaged fracture criterion and numerical implementation of limestone beam under three-point bending test

open access: yesFrontiers in Earth Science, 2023
To study the characteristics of tensile cracking by rock-bending damage, the bending stress–strain curves and the cumulative ringing counts were obtained by a three-point bending test and acoustic emission (AE) monitoring of limestone beams. Based on the

Descriptions of reversed yielding in bending [PDF]

open access: yes, 2007
Existence of Bauschinger effect in bending-unbending of copper beams has been shown from experiment. In modelling of the Bauschinger effect, it is shown that a significant second plastic penetration can occur with the release of the moment required for ...

Bent surface free energy differences from simulation

open access: yes, 2000
We present a calculation of the change of free energy of a solid surface upon bending of the solid. It is based on extracting the surface stress through a molecular dynamics simulation of a bent slab by using a generalized stress theorem formula, and ...
