The damping vibration characteristics of magneto-electro-viscoelastic (MEV) nanobeam resting on viscoelastic foundation based on nonlocal strain gradient elasticity theory (NSGT) is studied in this article. For this purpose, by considering the effects of Winkler-Pasternak, the viscoelastic medium consists of linear and viscous layers. with respect to the displacement field in accordance with th...

The load-transfer factor () in the concentric cylinder approach is often used analytical formulation axially loaded piles. a constant value (in given pile slenderness ratio and soil condition) devised under elastic ‘pre-failure’ perfect pile–soil bonding conditions (a non-slip model). Given most numerical methods have already considered slipping stage, limitations of models recently been discus...

Aircraft structures are made of thin-walled as it provides higher stiffness to weight ratio compared solid sections, but is prone buckling due its low and slenderness the individual element. One types that can impact integrity a beam lateral torsional which caused by simultaneous bending twisting cross-sections happens before beam's material strength reached. Therefore, design such structure sh...

To investigate the ultimate bearing capacity and deformation of recycled self-compacting concrete-filled circular steel tubular (RSCCFCST) long columns subjected to axial load, nine specimens with different concrete (RSCC) strength grades slenderness ratios are tested. The experimental results indicate that lateral deflection dominates buckling failure specimens. is enhanced gradually as RSCC g...

Due to the low specific strength of bamboo oriented strand boards compared with commonly used wooden building materials, reasonable and novel cross-section designs columns fabricated from as structural members were investigated. An axial compression experiment was carried out on full-scale characterize ultimate behaviors under a concentric load. The bearing capacities solid, hollow five-core sa...

abstract: In this paper, a computational tool was developed to optimize the design of slender reinforced concrete columns subjected biaxial bending considering material and geometric nonlinearities rigorously. The optimization process utilizes technique genetic algorithms find best cross-sectional dimension distribution amount reinforcement, minimize cost column subject certain constraints stre...

Understanding asymptotics of gradient components in relation to the symmetrized gradient is important for the analysis of buckling of slender structures. For circular cylindrical shells we obtain the exact scaling exponent of the Korn constant as a function of shell’s thickness. Equally sharp results are obtained for individual components of the gradient in cylindrical coordinates. We also deri...

Specific surface captures the combined effects of particle size and slenderness in a measurement that is independent and complementary to grain-size distribution. There are various methods to measure specific surface, including gas adsorption in dry conditions and selective molecular absorption in aqueous suspensions. The measurement procedure can have an important effect on measured values, ye...

ABSTRACT The addition of wedge-like fairings onto the side missiles and space launch vehicles, to shield devices such as cameras reaction jet nozzles, creates additional drag, particularly when in supersonic hypersonic freestream flow. An experimental computational study was performed obtain aerodynamic data on simple representative configurations test accuracy theories for drag increment due t...

This article examines the performance of Carbon Fibre Reinforced Polymer (CFRP) on Concrete Filled with Vinyl Chloride Tube (CFPT) columns under axial compression. Firstly, 44 CFPT specimens from literature were analyzed using ABAQUS software to understand compressive behavior applied displacement. Secondly, 268 are simulated influence CFRP these control a varying number FRP layers and wrapping...
