Engineering critical assessment of steel shell structure elements welded joints under high cycle fatigue
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Existing flaws in critical parts of structural elements may lead to failures of subassemblies and, in case of lack of redundancy, even to the entire structure collapse. Considering the case of cyclic loading - wind load ...
Experimental verification of performance of tip-jet helicopter propulsion system
(Elsevier, Amsterdam, 2020)
This paper presents the methodology for estimation of power delivery and efficiency of the tip-jet helicopter propulsion system. The main advantage of the tip-jet helicopter is the absence of heavy transmission and tail ...
Determination of the optimal production plan by using fuzzy AHP and fuzzy linear programming
(IOS Press, Amsterdam, 2020)
In this paper, we consider the problem of determining the optimal production quantity under uncertainties. The treated problem has a critical effect on the achievement of business goals, which further propagates to the ...
XFEM based analysis of fatigue crack growth in damaged wing-uselage attachment lug
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The research presented in this paper is based on the use of extended finite element method (XFEM) for stress intensity factors (SIFs) determination in the case of fatigue crack presented in the wing-fuselage attachment lug ...
Structural integrity and life assessment of rotating equipment
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Failures of rotating equipment often cause severe consequences, so it is necessary to study their integrity and life as detailed as possible, especially when crack is detected. In the case studied here, hydro power plant ...
Exposure model for European seismic risk assessment
(Sage Publications Inc, Thousand Oaks, 2020)
Building exposure and vulnerability models for seismic risk assessment have been the focus of a number of European projects in recent years, but there has never been a concerted effort among the research community to produce ...
Editorial - Damage, cracks and failure analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The 1st Virtual European Conference on Fracture (VECF1) has gathered more than 300 researchers from all over the world. They have presented more 320 papers, including 9 plenary lectures in the scope of the main VECF1 topics. ...
Process Mapping of Glass Envelope Design of Geometrically Complex Form
(Springer International Publishing Ag, Cham, 2020)
The design and construction of glass facades is a very complex sector in the construction industry, whose multidisciplinary character is reflected in the application of new technologies of glass and glass facade production, ...
Influence of the addition of different radiopacifiers and bioactive nano-hydroxyapatite on physicochemical and biological properties of calcium silicate based endodontic ceramic
(Elsevier Sci Ltd, Oxford, 2021)
The purpose of this study was to investigate the influence of different radiopacifiers on the physicochemical and biological properties of novel calcium silicate based endodontic ceramic enriched with bioactive nanoparticulated ...
The effect of time on mechanical properties of biocompatible photopolymer resins used for fabrication of clear dental aligners
(Elsevier, Amsterdam, 2021)
Clear dental aligners are used for treating orthodontic anomalies (misaligned teeth, inappropriate contact between upper and lower teeth etc.), minor irregularities and bruxism. Using additive manufacturing technologies ...
