Abstract A frequency accuracy study is presented for the isogeometric free vibration analysis of Mindlin–Reissner plates using reduced integration and quadratic splines, which reveals an interesting coarse mesh superconvergence. Firstly, error estimates discretization with splines are rationally derived, where degeneration to Timoshenko beams discussed as well. Subsequently, in accordance these...

This paper investigates the capacity of solid finite elements with independent interpolations for displacements and strains to address shear, membrane volumetric locking in analysis beam, plate shell structures. The performance proposed strain/displacement formulation is compared standard one through a set eleven benchmark problems. In addition relative both element formulations, studies effect...

A displacement-based finite element for the analysis of laminated composite beams is formulated using strain gradient notation. The definition of the beam’s longitudinal displacement possesses only the independent term (axial displacement) and a term which is linear in the thickness coordinate z. Thus, the finite element is first-order shear deformable. As strain gradient notation is physically...

introduction: direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. we compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (lfp) and lfpspike signals, respectively. methods: signals recorded from mt area of a macaque’s brain was used in a simulation app...

anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. the distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...

This paper reports numerical analyses of free vibration of laminated composite plate/ shell structures of various shapes, span-to-thickness ratios, boundary conditions and lay-up sequences. The method is based on a novel four-node quadrilateral element, namely MISQ20, within the framework of the first-order shear deformation theory (FSDT). The element is built by incorporating a strain smoothin...

The development of slip lines, due to strain localization, is a common cause for failure of soil in many circumstances investigated in geotechnical engineering. Through the use of numerical methods -like finite elementsmany practitioners are able to take into account complex geometrical and physical conditions in their analyses. However, when dealing with shear bands, standard finite elements d...

Introduction: Direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. We compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (LFP) and LFPspike signals, respectively.

Cardiomyocyte Monitoring In article number 2202235, Chunyu Chang, Donghui Zhang, and co-workers develop micropatterned hydrogels with anisotropic structural colors by locking shear-oriented tunicate cellulose nanocrystals (TCNCs) in hydrogel networks through situ polymerization. The autonomous beating of cardiomyocytes drives synchronous deformations the hydrogels, causing periodic changes tran...

Abstract In this paper, mixed formulations are presented in the framework of isogeometric Reissner–Mindlin plates and shells with aim alleviating membrane shear locking. The based on Hellinger-Reissner functional use stress resultants as additional unknowns, which have to be interpolated appropriate approximation spaces. unknowns can eliminated by static condensation. analysis condensation is p...
