IDR @ IIT Bhubaneswar
IDR @ IIT Bhubaneswar is the digital repository which archives research publications, annual reports and other digital contents of IIT Bhubaneswar. It is set up by using an open source digital repository software "DSpace" (developed by MIT & HP) that supports "Open Archives Initiatives Protocol for Metadata Harvesting" (OAI-PMH) and uses Dublin Core metadata.The repository is hosted and maintained by the Central Library, IIT Bhubaneswar.

In this article, the effects of damage (delamination) on the structural vibration characteristics of spar wingskin joints (SWJs) made with curved laminated composites are investigated. Three dimensional finite element analysis is employed to evaluate the natural frequencies and corresponding mode shapes of the joint structure considered. Virtual elements are implemented in the delamination region to prevent inter element penetration. The effectiveness of the finite element analysis technique ...
An experimental investigation is conducted to study the two-phase heat transfer behavior of a shear-thinning Non-Newtonian (NN) fluid, i.e., �Massecuite,� at atmospheric pressure over bi-directional microstructured surfaces for the heat flux range from 70 to 200�kW/m2. Two-phase heat transfer characteristics of a Newtonian Fluid, that is, distilled water, is also studied for the sake of comparison. Both aqueous XG solution and water exhibit higher heat transfer rate over microstructured surfa...
Experimental and numerical study of natural convection of air in a partially open square enclosure with two internal heat sources, located at the respective centers of the bottom wall and the right vertical wall, are performed. The left vertical wall, made up of an aluminum plate, has a partial opening that occupies 12.8%, 25%, and 50% of the wall. The effect of opening sizes and Rayleigh numbers on natural convective heat transfer is evaluated. The temperature distribution and the average Nu...
The exploitation of waste material in the production of cementitious composites such as mortar and concrete is featured as an emerging research area aiming to curtail cement requirements. This article focuses on the utilisation of ceramic waste for partial cement replacement, reviewing its influence on the corrosion and chemical attack resistance of cementitious composites. The reviewed literature majorly highlights an enhancement in corrosion and chemical attack resistance on exposure to sul...
In a multi-robot system, the appropriate allocation of the tasks to the individual robots is a very significant component. The availability of a centralized infrastructure can guarantee an optimal allocation of the tasks. However, in many important scenarios such as search and rescue, exploration, disaster-management, war-field, etc., on-the-fly allocation of the dynamic tasks to the robots in a decentralized fashion is the only possible option. Efficient communication among the robots plays ...
The Belle II experiment is taking data at the asymmetric SuperKEKB collider (KEK, Japan), which operates at the ?(4S) resonance. The vertex detector is composed of an inner two-layer pixel detector (PXD) and the silicon vertex detector (SVD), made of four layers of double-sided silicon strip detectors. A deep knowledge of the system has been gained since the start of operations in 2019 by assessing the high-quality and stable reconstruction performance of the detector. The very high hit effic...
The high-velocity impact performance of honeycomb sandwich structures is enhanced by adopting multi-stage structures with varying cell wall thickness, and cell wall inclination, after preserving the structural mass. The performance of the enhanced structures is simulated considering bullet penetration tests. The penetration is observed to be reduced by 4.82% in case of two stage sandwich structures, as compared to the single stage sandwich structures. Furthermore, the reduction in penetration...
This paper introduces a finite spectral element method for a single edge notch cracked extended Timoshenko beam for wave propagation analysis and damage detection. The crack introduced is a transverse open and non-propagating crack. The cracked region is discretized in a mass-less and dimension-less spring element. The quantity of damage implemented is expressed in terms of crack flexibility based on fracture mechanics. In the damage region, the compatibility conditions are satisfied. This pr...
Optical interferometry integrated with molecularly imprinting polymer (MIP) can be an advanced futuristic approach for developing ultrasensitive and selective remote detection technology. This cohesive strategy has enormous potential for developing next-generation online biomolecule detection systems riding on the benefits of artificial complementary polymeric nanostructure with outstanding durability, easy synthesis process, and sustainability in harsh environmental conditions. Here, we have...
Attaining the ferroelectric (FE) polarization in a thin HfO2 layer using a specific dopant is a widely adopted way to realize Negative Capacitance (NC) FET. In a general TCAD simulation study of NC-based devices, the NC property of the FE layer is strongly dependent on the values of Landau parameters (?,?,?,?,g), which are unique for specific dopants and FE thickness. In this paper, for the first time, we investigated the reliability of TCAD simulations with which NC FinFET is simulated for a...
