The aim of this article is to analyse the nonlinear biomechanics diseased carotid arteries as a potential tool for predicting onset cerebral strokes. A two-way coupled three-dimensional (3D) hyperelastic fluid-structure interaction (FSI) analysis artery with abnormal luminal projections at bulb known web (CaW) conducted on geometry patient artery, built upon employing CT angiography images. blood-flow model incorporates non-Newtonian pulsatile turbulent fluid, and wall considered subject blood-induced motion. hemodynamics induced by transient boundary conditions determined, specifically focusing shifts in crucial hemodynamic parameters such shear stress (WSS) alterations blood velocity pattern. Structural assessment involves quantifying von Mises (VM) deformation field. demonstrates that different CaW models result flow patterns selection time steps cardiac cycle. findings reveal presence web, most common disease among younger adults, can significantly influence potentially accelerate formation thrombus atherosclerosis. Hemodynamic predict specific sites prone plaque rupture within artery.

This study presents an original and novel investigation into the mechanics of piezo-flexo-magneto-elastic nanocomposite doubly-curved shells (PFMDCSs) ability to detect lower higher levels electro-magnetic fields. In this context, by utilizing first-order shear deformation shell model, stresses strains are acquired. By imposing Hamilton's principle von Kármán approach, governing equations have been obtained. The intelligent model consists size-dependent influences, viz., strain gradients. will take place via Mindlin's gradient elasticity theory subsequent re-establishing mathematical framework incorporating concept. results in a flexoelectric/flexomagnetic effect. converse effect magnetic field on basis close circuit has assumed. developed bending transferred algebraic ones substituting analytical technique based homogeneous immovable simple support for four edges. problem solved according Newton-Raphson iteration scheme, transverse deflections computed. For researching rightness precision models together with solution process, comparison is prepared finite element method (FEM) simplified shells, good correlation observed. At last, examining several factors problem, conditions under which effects can be noticeable dominant sought. could serve as benchmark reference piezoceramic-DCSs, presented original. most interesting outcome research that response structures entirely geometry-dependent.

The focus of this study is on the nonlinear mechanical properties epoxy and epoxy-based nanocomposites, exploring frequency strain amplitude dependency. Nanocomposite samples are reinforced with fumed silica (FS), halloysite nanotubes (HNT) Albipox 1000 rubber (Evonik) nanoparticles. Considering these particles have different geometries stiffnesses, they expected to significantly influences mechanics resulting composite. To enhance reliability results reveal impact nanofillers material more distinctly, manufacturing process designed be same for all specimens within groups eliminate effects process. comprehensive characterization consists Fourier-Transform InfraRed Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) Dynamic Mechanical Analysis (DMA). DMA tests so that measured depending vibration amplitude. Finally, characterized dynamic nanocomposites used as input into a numerical model. In simulation, cantilever beam representative properties, created, example its forced response plotted under levels excitation in domain. Key identified using resonance behavior, primarily focusing stiffness damping nanocomposites. These experimental procedures followed show significant nanoparticle reinforcements nature composites.
