Assessment of compressive strength, durability, and erodibility of quarry dust-based geopolymer cement stabilized expansive soil
Multiscale and Multidisciplinary Modeling, Experiments and Design - Tập 5 - Trang 81-90 - 2021
The effect of quarry dust-based geopolymer cement on the compressive strength, erodibility, and durability potential of expansive soils has been studied under laboratory conditions. The particular interest was on the geopolymer cement treatment of soils subgrade under hydraulically bound environments. Lateritic soils, which form the compacted foundation of pavements, tend to swell upon contact wit...... hiện toàn bộ
Performance enhancement of junctionless silicon nanotube gate-all-around FETs for nano-scaled devices
Multiscale and Multidisciplinary Modeling, Experiments and Design - - 2024
This paper presents a novel structure of TSV-based silicon nanotube gate-all-around FETs (both junction-based and junctionless) along with their electrical characteristics using Silvaco ATLAS 3D device simulator. In comparison, the junctionless silicon nanotube gate-all-around structures presented an excellent performance improvement over the junction-based structures in terms of short channel eff...... hiện toàn bộ
Optimum design of vibration absorber for cracked beam under the effect of moving concentrated force utilizing genetic optimization algorithm
Multiscale and Multidisciplinary Modeling, Experiments and Design - - Trang 1-8 - 2023
This study presents a multi-objective optimization method for designing a vibration absorber to reduce the vibrations of a cracked Euler–Bernoulli beam with flexible support under moving forces. Using the assumption of an open crack, the crack is modeled as a decrease in cross-sectional flexibility. After adding an absorber to the beam, the effect of cracks with different intensities on its vibrat...... hiện toàn bộ
Modelling of heat-affected zone (HAZ) in CO2 laser micromachining of aluminium-coated polymethyl methacrylate (PMMA) using adaptive neuro-fuzzy inference system (ANFIS)
Multiscale and Multidisciplinary Modeling, Experiments and Design - - Trang 1-13 - 2023
Heat-affected zone (HAZ) has adverse effects on the bonding of microfluidic devices and the transmission of fluids through the devices during operation. This results in microfluidic products of poor quality and low accuracy. This study employed adaptive neuro-fuzzy inference system (ANFIS) to investigate HAZ in CO2 laser micromachining of polymethyl methacrylate (PMMA). An aluminium wire of 99.95%...... hiện toàn bộ
Experimental and numerical evaluation of punching strength of RC flat slabs strengthened using FRP fabrics
Multiscale and Multidisciplinary Modeling, Experiments and Design - - Trang 1-12 - 2023
Punching failure is the critical phenomenon in isolated footing as well as in flat slabs, because of high shear concentration near the column vicinity. Numerous existing flat slab structures have inadequate performance, which may be resulted on by changes in accommodations, poor design and construction methods, noncompliance with new codal guidelines, etc. One possible way of enhancing structural ...... hiện toàn bộ
Heat transfer in material having random thermal conductivity using Monte Carlo simulation and deep neural network
Multiscale and Multidisciplinary Modeling, Experiments and Design - - 2024
Stochastic heat transfer simulations play a pivotal role in capturing real-world uncertainties, where randomness in material properties and boundary conditions is present. Traditional methods, such as Monte Carlo simulation, perturbation methods, and polynomial chaos expansion, have provided valuable insights but face challenges in efficiency and accuracy, particularly in high-dimensional systems....... hiện toàn bộ
Compliant damper development for vibration reduction in turning of aluminium
Multiscale and Multidisciplinary Modeling, Experiments and Design - - Trang 1-10 - 2023
Mechanical structures consist of more number of links, joints and elements combined through operations, such as welding, reverting, fastening etc. Owing to large service periods, these joints would eventually develop stresses internally and thereby joint failure occurs. The complaint damper can be used to reduce joint failure A compliant is a seamless single entity completely made of homogenous ma...... hiện toàn bộ
RETRACTED ARTICLE: Gas tungsten constricted arc welding (GTCAW) parameters optimization to attain maximum tensile strength in Ti–6Al–4V alloy sheets used in aero-engine components
Multiscale and Multidisciplinary Modeling, Experiments and Design - Tập 2 - Trang 291-291 - 2019
Parametric optimization of non-traditional machining processes using multi-criteria decision making techniques: literature review and future directions
Multiscale and Multidisciplinary Modeling, Experiments and Design - Tập 6 - Trang 1-40 - 2022
Continuous urge for generation of complex intricate features on harder and tougher materials with close dimensional tolerance and superior surface quality has led to the development of non-traditional machining (NTM) processes. Unlike the conventional machining processes, the NTM processes employ energy in various forms or their combinations for removal of material from the workpiece. As these pro...... hiện toàn bộ
A computational analysis of heat transfer in solid and vented disc brakes: CFD simulation and thermal performance assessment
Multiscale and Multidisciplinary Modeling, Experiments and Design - - 2024
This research presents a computational approach to estimate the heat transfer of solid and vented brake discs. Based on research data, it has been observed that when driving at slower speeds, a vented rotor’s effectiveness in cooling greatly decreases, with most of the cooling being generated by the additional surface area. The measurement of heat transfer in commercial vehicle disc brakes is dete...... hiện toàn bộ
