Contact mechanics of fractal surfaces by spline assisted discretisation

open access: yesInternational Journal of Solids and Structures, 2015
We present a newly developed approach for the calculation of interfacial stiffness and contact area evolution between two rough bodies exhibiting self affine surface structures. Using spline assisted discretization to define localised contact normals and surface curvatures we interpret the mechanics of simulated non-adhesive elastic surface-profiles ...

The Rational Spline Interpolation Based-LOD Method and Its Application to Rotating Machinery Fault Diagnosis

open access: yesApplied Sciences, 2020
Local oscillatory-characteristic decomposition (LOD) is a relatively new self-adaptive time-frequency analysis methodology. The method, based on local oscillatory characteristics of the signal itself uses three mathematical operations such as ...

3D Reality-Based Survey and Retopology for Structural Analysis of Cultural Heritage

open access: yesSensors, 2022
Cultural heritage’s structural changes and damages can influence the mechanical behaviour of artefacts and buildings. The use of finite element methods (FEM) for mechanical analysis is largely used in modelling stress behaviour. The workflow involves the

Analysis of the approaches used for calculating involute splined couplings and the methods of considering their influence on the dynamic behavior of systems

open access: yesНаучный вестник МГТУ ГА, 2023
Spline couplings, due to their high reliability and strength parameters, are widespread not only in mechanical engineering. The ability to transmit high torque with a sufficiently long service life has led to the extensive use of these couplings in the ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Analysis of stress-strain state of the metal plate based on discrete data of displacement values

open access: yesФізика і хімія твердого тіла
An actual problem of stress-strain state (SSS) analysis of a bent metal plate under an uncertain acting load is solved.  A problem in the direct use of spatial interpolation for obtaining the surface of a metal plate, which is realized in the Surfer ...

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...
