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 ...
An overview of application of micromechanical models in ductile fracture analysis of welded joints
(Srpsko društvo za mehaniku, Beograd, 2020)
Fracture of welded joints has been an important research and industrial topic for a long time, having in mind the key role of welded joints in ensuring the safe operation and integrity of welded structures. This work ...

(Ekonomski institut, Beograd, 2020)
U savremenim uslovima poslovanja organizaciona kultura prepoznata je kao moćno sredstvo za dugoročni opstanak i razvoj organizacije. Svrha ovog rada bila je istražiti da li i na koji način karakteristike organizacija - ...
Kinetic parameters identification of conductive enhanced hot air drying process of food waste
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal ...
Upgrade of the thermal power plant flexibility by the steam accumulator
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Thermal power plants are forced to operate under frequent load changes in energy systems with increased share of solar and wind power plants. These load changes increase thermal power plant aging and reduce their efficiency. ...
Derivation of Elastic Constants for Orthotropic Plates
(Korean Soc Steel Construction-Kssc, Seoul, 2020)
The paper presents a procedure for modeling an orthotropic thin plate finite element so to have an equivalent structural response as the steel stiffened plate of same overall dimensions. New, equivalent element, homogenizes ...
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 ...
Life cycle assessment of wood chips supply chain in Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Two most common systems of forest biomass supply chains in Serbia are evaluated by using the Life Cycle Assessment (LCA) approach: 'cut-to-length' system with penduculate oak (CLO) on flat terrains with a tractor equipage, ...
Explosive boiling of water films based on molecular dynamics simulations: Effects of film thickness and substrate temperature
(Elsevier, 2023)
This paper deals with investigations of mechanisms governing explosive boiling of water films on hot copper substrate with plain surface. The investigations are based on results of molecular dynamics (MD) simulations in ...
Experimental Evaluation of Hoop Stress–Strain State of 3D-Printed Pipe Ring Tensile Specimens
(MDPI, 2022)
Data on the strain and stress status of the pipe in the circumferential direction are required for various pipe manufacturing procedures (e.g., in the oil business, the process of manufacturing seamless pipes with a conical ...
