A new approach to reduce membrane and transverse shear locking for one-point quadrature shell elements: linear formulation

International Journal for Numerical Methods in Engineering, 2006
In the last decade, one-point quadrature shell elements attracted many academic and industrial researchers because of their computational performance, especially if applied for explicit finite element simulations.

Effects of AC induced electric fields on neuronal firing sensitivity and activity patterns [PDF]

Frontiers in Computational Neuroscience
IntroductionUnderstanding how neurons respond to time-varying electric fields is essential for both basic neuroscience and the development of neuromodulation strategies. However, the mechanisms by which alternating-current induced electric fields (AC-IEF)

Removing membrane locking in quadratic NURBS-based discretizations of linear plane Kirchhoff rods: CAS elements

Computer Methods in Applied Mechanics and Engineering, 2022
NURBS-based discretizations suffer from membrane locking when applied to primal formulations of curved thin-walled structures. We consider linear plane curved Kirchhoff rods as a model problem to study how to remove membrane locking from NURBS-based discretizations.

A simple and efficient hybrid discretization approach to alleviate membrane locking in isogeometric thin shells

Computer Methods in Applied Mechanics and Engineering
This work presents a new hybrid discretization approach to alleviate membrane locking in isogeometric finite element formulations for Kirchhoff-Love shells. The approach is simple, and requires no additional dofs and no static condensation. It does not increase the bandwidth of the tangent matrix and is effective for both linear and nonlinear problems.

Membrane Tension Locks In Pluripotency [PDF]

Cell Stem Cell, 2021
In this issue of Cell Stem Cell, De Belly et al. (2021) and Bergert et al. (2021) reveal that membrane tension regulates the pluripotent state via endocytosis-mediated ERK signaling. These findings advance our understanding of naive pluripotency and highlight how cell mechanics are intertwined with molecular signaling to drive cell fate decisions.

Postoperative transverse sternal nonunion with a chest wall defect managed by a tibial locking plate and a Gore-Tex dual mesh membrane: a case report

Journal of Cardiothoracic Surgery, 2021
Background Transverse sternal nonunion is a rare but disabling complication of chest trauma or a transverse sternotomy. Fixation methods, mainly used to manage the more common longitudinal sternal nonunion, often fail, leaving the surgical treatment of ...

An 8-Node Solid-Shell Finite Element based on Assumed Bending ‎Strains and Cell-Based Smoothed Membrane Strains for Static Analysis of Plates and Shells [PDF]

Journal of Applied and Computational Mechanics, 2020
In this paper, a new 8-node solid-shell finite element is proposed. The transverse shear strains and transverse normal strains of the element are separately interpolated and related to the C0-displacement approximation at tying points to overcome the ...

TEMPOROMANDIBULAR JOINT SYNOVIAL CHONDROMATOSIS: A RARE CASE

Cumhuriyet Dental Journal, 2021
Synovial chondromatosis (osteochondromatosis) is a rare lesion originating from the synovial membrane. It develops as a result of metaplasia of the tendon sheath or synovial membrane of the bursa in the joint and causes the formation of chondral or ...

Static and buckling analyses of stiffened plate/shell structures using the quadrilateral element SQ4C

Comptes Rendus. Mécanique, 2020
In the present study, a novel quadrilateral element, namely SQ4C, combined with the Timoshenko beam element is proposed for the static and buckling analyses of stiffened plate/shell structures.
