A Methodology for daylight optimisation of high-rise buildings in the dense urban district using overhang length and glazing type variables with surrogate modelling
( Institute of Physics Publishing , 2019 , Conference Paper)Urbanization and population growth lead to the construction of higher buildings in the 21st century. This causes an increment on energy consumption as the amount of constructed floor areas is rising steadily. Integrating ... -
Drill string nonlinear vibrations: Experimental studies and finite-element analysis
( Institute of Physics Publishing , 2018 , Conference Paper)In the present work, nonlinear vibrations of drill strings are studied. A laboratory scale arrangement consisting of a flexible rod with rotor-stator system is used to study the system dynamics. A finite-element model has ... -
Dynamic response of functionally graded graphene nanoplatelet reinforced shells with porosity distributions under transverse dynamic loads
( Institute of Physics Publishing , 2019 , Article)This article investigates forced vibrational characteristics of a porous nanocomposite shell reinforced by graphene platelets (GPLs) under radial dynamic loads. Material properties of the shell dependents on uniform and ... -
Energy absorption capabilities of complex thin walled structures
( Institute of Physics Publishing , 2017 , Conference Paper)Thin walled structures have been used in the area of energy absorption during an event of a crash. A lot of work has been done on tubular structures. Due to limitation of manufacturing process, complex geometries were ... -
Enhancing the damping effect of MRF damper using an external magnetic excitation system
( Institute of Physics Publishing , 2023 , Article)The magnetic field generated by the damper’s magnetic circuit governs the yield stress value of the Magnetroholgical Fluid (MRF) damper and hence its damping effect. This paper contributes to the literature on the development ... -
Investigating the characteristics of a magnetorheological fluid damper through CFD modeling
( Institute of Physics Publishing , 2021 , Article)Computational Fluid Dynamics (CFD) analysis is conducted on mono-tube vehicle MRF damper investigated experimentally in a previous study. In this study, the fluid of the type MRF-132DG was inserted inside a damper of a car ... -
Measurements of Elastic Properties of Biological Hydrogels using Atomic Force Microscopy
