Effect of the crystallinity of diamond coatings on cemented carbide inserts on their cutting performance in milling
(Elsevier Science Bv, 2019)Micro-crystalline diamond (MCD) coatings were deposited on cemented carbide inserts at different temperatures using hot filament chemical vapor deposition technique. For investigating the effect of the developed diamond ... -
Numerical and experimental analysis of a heat-pipe-embedded printed circuit board for solid state lighting applications
(Taylor & Francis Inc, 2019)Thermal management is one of the main issues for electronics cooling especially for tightly packaged PCBs that experience local heat generation. Thus, theoretical and experimental investigations have been conducted to ... -
An experimental and analytical study on the influence of superhydrophobic micro-textured surfaces on liquid wetting phenomena
(Elsevier Science Bv, 2018)Controlling dust, particle, gas or liquid attachment or motion over the surfaces is attracting many researchers to reduce losses or reach mission-specific goals. Therefore, researchers have been developing novel surfaces ... -
A hyperelastic constitutive model for rubber-like materials
(Springer, 2020)Hyperelastic behavior of isotropic incompressible rubbers is studied to develop a strain energy function which satisfies all the necessary characteristic properties of an efficient hyperelastic model. The proposed strain ... -
Impact of functional nanofluid coolant on radiator performance
(Asme, 2019)While a number of liquids are preferred in many heating and cooling applications, their thermal capacity can be a limiting factor in many thermal systems. Therefore, a series of methods such as use of mixtures of two or ... -
Characterization of stress softening and self-healing in a double network hydrogel
(Elsevier, 2019)In this paper, a micro-mechanically based constitutive model is presented to describe stress softening and self-healing in alginate-polyacrylamide (PAAm) double network (DN) hydrogels. The stress softening phenomenon in ... -
Cutting performance improvement of MTCVD coated cemented carbide inserts via appropriate heat treatment
(Elsevier, 2020)The softening of cemented carbide at the elevated temperature of MTCVD processes results in significant reduction of their strength, and thus, high coating deformation during cutting. In this way, at interrupted cutting ... -
Gas-driven thin liquid films: effect of interfacial shear on the film waviness and convective heat transfer
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2019)This study is aimed at experimental investigation of hydrodynamics and convective heat transfer in gravity and gas-driven thin liquid wall films. The liquid film has been annularly applied on a vertically aligned heated ... -
Evaluation of NaOH pre-treatment on the corrosion behavior and surface characteristics of hydroxyapatite coated NiTi alloy
(Springer Heidelberg, 2020)Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ... -
Effect of polymer coating on vapor condensation heat transfer
(Asme, 2020)Condensation heat transfer coefficients (HTCs) are rather low compared to thin film evaporation. Therefore, it can be a limiting factor for designing heat transfer equipment. In this work, heat transfer characteristics of ... -
A constitutive model for hysteresis: the continuum damage approach for filled rubber-like materials
(Springer, 2020)In this contribution, a constitutive model is proposed for filled rubber-like materials to describe hysteresis. The model is based on the network decomposition concept. Rubber matrix is decomposed into purely elastic and ... -
Stiffening of biopolymer aerogel networks upon wetting: a model-based study
(Elsevier, 2020)The mechanism behind the stiffening effect observed in the stress-strain response of alginate-starch aerogels upon being exposed to wetting is investigated in this paper, via a physically motivated model approach. A network ... -
Stress, strain and strain-rate cemented carbide properties determined with a fem-supported evaluation of impact test imprints
(Elsevier Sci Ltd, 2021)Cemented carbide materials are key in tool manufacturing, nowadays widely used in cutting, forming and other manufacturing processes. Commonly applied methods for obtaining their strain-rate dependent material properties ... -
Spreading behavior of droplets impacting over substrates with varying surface topographies
(Elsevier, 2020)Droplet interaction with solid surface plays an important role in a number of practical applications such as thermal management systems, steel production, painting, prevention of impurit deposition, and formation of ... -
An experimental and theoretical analysis of vapor-to-liquid phase change on microstructured surfaces
(Pergamon-Elsevier Science Ltd, 2020)In this work, an experimental and a theoretical study was carried out on condensation heat transfer on vertically aligned bare unstructured, micro V-grooved and square-grooved copper substrates. During the experiments, ...
