CFD Calculation of Helicopter Tail Rotor Airloads for Fatigue Strength Experiments
(Asce-Amer Soc Civil Engineers, Reston, 2017)
This work focuses on defining loads and fatigue life estimation of helicopter tail rotor blades. The original metal construction of these blades was replaced with a new construction of blades made from composite materials. ...
Determining the crack acceptability in the welded joints of a wind loaded cylindrical steel shell structure
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Engineering critical assessment can be considered as a mandatory request in the civil engineering designing and manufacturing process. The paper is presenting the procedure for determination of crack acceptability based ...
Influence of plasma spraying parameters on properties of thermal barrier coatings
(Taylor & Francis Ltd, Abingdon, 2013)
The aim of the present study is to investigate the influence of plasma spay deposition parameters on various properties of two standard thermal barrier coating (TBC) systems deposited on the steel substrate. Two TBC systems ...
The resistance to crack growth of different regions of weldments in a real structure
(International Journal of Pressure Vessels and Piping, 1992)
The growth of a crack in regions of welded joints, made from high-strength low-alloy steel, has been analysed on specimens and full-scale structures. The effect of such crack growth on the safety of welded steel pressure ...
Hydroxyapatite-based dental inserts: Microstructure, mechanical properties, bonding efficiency and fracture resistance of molars with occlusal restorations
(Wiley, 2023)
This study aimed to (1) comparatively analyze properties of Sr- and Mg-substituted hydroxyapatite (HAP)-based dental inserts; (2) evaluate insert bonding to restorative materials, and (3) evaluate the effect of doped HAP ...
High-temperature deformation behaviour of Ti3Al-11Nb intermetallic
(Carl Hanser Verlag, Munich, 2011)
A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish ...
Influence of secondary phases in A356 MMCs on their mechanical properties at macro- and nanoscale
(Springer Heidelberg, Heidelberg, 2020)
Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, )
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
The Influence of Modifying Methods on the Quality of Eutectic and Hypereutectic Silumine for Diesel Engine Pistons
(International Journal of Cast Metals Research, 2013)
The results of the investigation of the influence of different modifiers (sodium, phosphorus, antimony and strontium) on the quality of AlSi12CuMgNi and AlSi18CuMgNi alloys, which are used for the production of pistons, ...
Comparison of cavitation erosion behavior od cordierite and zircon based samples using image and morphological analyses
(Materials Letters, 2018)
In this study the resistance of cordierite and zircon to the cavitation erosion was investigated with the aim of possible spreading their application. Cavitation erosion test was applied using standard ultrasonic vibratory ...
