The role of drainage systems in the prevention of material degradation of bridge structures
(XXIII YuCorr, Divčibare, Serbia, 2022)
The paper gives an illustrative presentation of damage to the material of bridge structures
due to failure to maintain the system for drainage of bridges. Damage is caused by mechanical
erosion and abrasion or by chemical ...
Bucket wheel excavators_Dynamic response as a criterion for validation of the total number of buckets
(Engineering Structures, 2020)
An original method for validation of the number of buckets on the working device of a bucket wheel excavator based on the dynamic response of its slewing superstructure (SS) is presented. A set of 16 seemingly acceptable ...
Examination of the physical-chemical and mechanical properties of helical cylindrical compression springs preserved in the Legacy in the Nikola Tesla Museum
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
The results of the scientific research work and creativity of Nikola Tesla (Smiljan, 1856 - New York, 1943), a Serbian-American scientist, engineer and inventor, represent the foundation of new technical and technological ...
Analysis of contact fatigue coupled with geometry and material nonlinearities by Theory of critical distances
(2nd Conference on Nonlinearity, Belgrade, 2022)
The contact fatigue is a localized phenomenon that occurs in highly
stressed local zone of the material under the loaded contact region and as such is
highly nonlinear problem. This phenomenon exists in almost all real ...
Experimental research of mechanical characteristics of railway vehicles safety coupling components
(International Conference of Experimental and Numerical Investigations and New Technologies CNN TECH 2021, Zlatibor, Serbia, 2021)
The coupling system provides a mechanical connection between European railway vehicles. Screw couplings are designed as a safety device in railway vehicles with coupling links and screw as two main components intended to ...
Neural network model for the condition assessment of hydro turbines
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
During regular operation, hydro turbine elements have complex operating conditions. In order to prevent major failures, among other common preventive measures, it is necessary to make a useful model of hydro turbine. ...
Analysis of Hertz contact stresses for metallic material with carbides
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
Hertz contact and the resulting stress-strain state arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental ...
Geometric optimization of shaft transition zone based on stress-strain analysis of nature inspired design
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
The presented research primarily considers with the geometric solutions that Nature has optimized. In the study presented in this paper, the nature inspired transition shapes are used in the research of innovative design ...
Assessing technological properties and environmental impact of fired bricks made by partially adding bottom ash from an industrial approach
(Elsevier Ltd, 2023)
Over the past few decades, the fired clay brick industry has searched for industrial wastes to substitute raw clay deposits and lessen their impact on the environment. Despite several investigations showing positive results, ...
Experimental determination and numerical validation of the critical value of the J-integral ofa low carbon microalloyed steel for elevated temperature application
(VIII INTERNATIONAL CONGRESS ENGINEERING, ENVIRONMENT AND MATERIALS IN PROCESS INDUSTRY EEM 2023, 2023)
To evaluate the behavior of a homogeneous material in the presence of a crack-type defect, the
value of the critical stress-intensity factor, KIc, was determined as a measure of the fracture
toughness of the tested steel ...
