Welded joint geometry effect on fatigue crack growth resistance in different metallic materials
(Elsevier Sci Ltd, Oxford, 2021)
Fatigue crack growth through different welded joint regions was investigated, in terms of welded joint geometry and fatigue crack position. In the first phase of investigation, numerical simulation of crack growth in a ...
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 ...
Comparison of experimental, numerical and analytical risk assessment of oil drilling rig welded pipe based on fracture mechanics parameters
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Fracture mechanics parameters are used for experimental, numerical and analytical risk assessment of structural integrity and life of oil drilling rig welded pipe with a crack. As a simple analytical tool, the Failure ...
Human factor risk management procedures applied in the case of open pit mine
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Risk management aims to provide a controlled work environment to ensure the safe operation of the high-risk systems. It is a dynamic process which work in a continual state of change. The issue of human factor risk and ...
Determination of the Actual Stress-Strain Diagram for Undermatching Welded Joint Using DIC and FEM
(MDPI, Basel, 2021)
This paper presents new methodology for determining the actual stress-strain diagram based on analytical equations, in combination with numerical and experimental data. The first step was to use the 3D digital image ...
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 ...
Chaotic fruit fly optimization algorithm
(Elsevier, Amsterdam, 2015)
Fruit fly optimization algorithm (FOA) is recently presented metaheuristic technique that is inspired by the behavior of fruit flies. This paper improves the standard FOA by introducing the novel parameter integrated with ...
A contribution to the optimal numbering of a ring structure
(Computers and Structures, 1988)
An optimal element numbering of a pipeline system containing rings is considered. In order to minimize the front width two possible cases of ring structure are analysed and solved in different manners. An example is shown ...
New insights into physics of explosive water boiling derived from molecular dynamics simulations
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
In this paper the dynamics of explosive boiling of a 72 angstrom thick water film on the hot copper substrate with the plain surface is analysed. The analyses are based on the results of molecular dynamics (MD) simulations ...
