Experimental and numerical study on the thermoforming process of amorphous thermoplastic polymers
(Carl Hanser Verlag, 2019)
Thickness distribution has an important impact on the quality of thermoformed products. It has significant effects not only on durability but also on the oxygen and gas transmission rate of thermoformed packaging products. ...
Process damping model approach in milling operations
(Springer Heidelberg, 2021)
The subject of this study is a new Process Damping Model approach for milling with flat end milling cutter. Dynamic model of the cutting system was modeled and applied for the milling operation. The machining process is ...
Design of a broadband elastic metamaterial via topologically optimized inertial amplification mechanisms
(European Association for Structural Dynamics, 2020)
Elastic metamaterials enable to generate phononic band gaps below the Bragg limit. Most metamaterials in the literature are based on vibration absorption (local resonance) principle. In this study, a two dimensional elastic ...
Use of Image Analysis for Non-Destructive Testing of Thermoformed Food Packages
(Walter de Gruyter GmbH, 2021)
The aim of this study is to determine the thickness distribution of a food package using a non-destructive method. Initially, thickness measurements were carried out using an experimental procedure for thermoformed samples ...
Effects of infill pattern and density on wear performance of FDM-printed acrylonitrile- butadiene-styrene parts
(Walter De Gruyter Gmbh, 2021)
Acrylonitrile-butadiene-styrene test specimens were additively manufactured by fused deposition method to investigate the effects of infill pattern and density on wear rate, coefficient of friction, wear mechanisms, and ...
Effect of temperature on wear behavior of multilayered thin cr-coated acrylonitrile-butadiene-styrene polymer: An experimental and prediction study
(ASTM International, 2022)
The wear behavior of thin chromium-coated and uncoated acrylonitrile-butadiene-styrene (ABS) samples were investigated by using a pin-on-disk test apparatus with a heat chamber for different temperatures of 30°C, 50°C, ...
The Effect of Temperature on Wear Performance of High-Velocity Oxy-Fuel Sprayed WC-10Co-4Cr Coating on AA7075-T6 Substrate
(Springer, 2021)
In this study, the friction wear performance of a High-velocity oxy-fuel (HVOF) sprayed WC-10Co-4Cr coated AA7075-T6 substrate was investigated against a WC-4Co ball at different temperatures using a pin-on-disk tribometer. ...
Drying of Prina Using Microwave Energy and Determination of Appropriate Thin Layer Drying Model
(Univ Namik Kemal, 2015)
This study examined the thin layer drying kinetics of the prina in the microwave. Prina samples with 7mm, 9mm and 11mm thickness were dried using 90, 180, 360 and 600 W (2450 MHz) microwave output powers and changing of ...
Modelling of dynamic cutting force coefficients and chatter stability dependent on shear angle oscillation
(Springer London Ltd, 2017)
Productivity of high-speed turning operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting tool ...
CFD modelling and experimental validation of cell performance in a 3-D planar SOFC
(Pergamon-Elsevier Science Ltd, 2019)
Fuel cells can be used to provide power for most electrical or electronic devices designed for operation from batteries or from conventional utility power sources. In this study, a three dimensional Computational Fluid ...
