Nanomaterials for sustainable energy production and storage: Present day applications and possible developments
(Springer International Publishing, 2017)
Currently used technologies in energy industry are oftentimes potentially harmful for the environment and/or not sustainable in the long run (e.g. fossil and mineral based fuels, nuclear energy). Therefore the oncoming ...
Primary control reserve of electric power by feedwater flow rate change through an additional economizer - A case study of the thermal power plant "Nikola Tesla B"
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Coal-fired thermal power plants (TPPs) had been generally designed to cover base loads of electricity consumption. Nowadays, they should be flexible to participate in the primary frequency control of electric system, ...
Possibility of Reducing the Overpressure of Shock Wave of Powder Gases around the Mortar
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
This paper resulted from the research of the overpressure of the shock wave of the powder gases, which occurs during firing of the mortar. Work encompasses modeling and computation of the overpressure field. Increasing ...
XRF and LIBS measuring on metal and ceramic laser-cleaned surfaces
(IMEKO-International Measurement Federation Secretariat, 2016)
The use of lasers in the conservation of artefacts plays an important role since its posibilities of safe, efficient and efective cleaning on complex surfaces and wide range of materials. This paper presents the results ...
Creep crack growth - Comparison of two steel P91 and P22
(International Conference on Fracture, 2017)
The deformation and crack growth behaviour of P22 and P91 steel weldments tested at 550 °C and 600 °C, respectively,compact C(T) type specimens with sharp EDM starter notches in the base metal (BM) and heat affected zone ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Workspace design for crane cabins applying a combined traditional approach and the Taguchi method for design of experiments
(Taylor & Francis Ltd, Abingdon, 2016)
Procedures in the development process of crane cabins are arbitrary and subjective. Since approximately 42% of incidents in the construction industry are linked to them, there is a need to collect fresh anthropometric data ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(International Conference on Fracture, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
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. ...
Temperature and time effects on fracture toughness values in welded joint
(International Conference on Fracture, 2017)
Temperature and time effects on fracture toughness have been investigated for characteristic regions in a welded joint made of Cr-Mo steel A-387 Gr. B. Comparative analysis of fracture toughness values for characteristic ...
