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 ...
Failure analysis of ATR 72 tow bar–opportunity for re-design for inspection
(10th EASN Virtual International Conference on Innovation in Aviation & Space to the Satisfaction of the European Citizens, 2020)
The safe towing of aircraft is an important part in aviation security. Failures during the towing and parking
related operations are not so rare due to bad working circumstance, human error, etc. Tow bars are simple
but ...
Comparative analysis of current standards for testing thermal protection of facade carpentry
(Regional Association for Security and Crisis Management-RASEC S4 GLOSEC Global Security, 2021)
The low level of energy efficiency in buildings results in increased energy
consumption for heating and cooling and high carbon dioxide emissions. Insufficient
thermal protection of the exterior of a building contributes ...
Experimental analysis of fire resistance of cly hollow-brick masonsry non-load bearing wall
(Proceeding of the 8th International Conference "Civil engineering-science and practice", Kolašin, 2022)
Testing the clay hollow-brick masonry non-load-bearing wall helps us to understand the behaviour of this type of wall during a fire. It is important to know the fire resistance of hollow brick walls so that we can prevent ...
Testing of building materials - reaction to fire
(Proceedings of the 17th Conference with International participation risk and safety engineering, Kopaonik, 2022)
To reduce occurrence of fires in buildings as efficiently as possible, it is necessary to take into account active and passive fire protection measures during construction of building. This paper will show more about passive ...
Fire protection of health facilities
(Proceedings of the the 17th International Conference on fire and explosion protection and the 7th International Scientific Conference on safety engineering – fire, environment, work environment, integrated risks, Kladovo, 2021)
Critical infrastructure can be demaged, destroyed or disrupted by deliberate acts of natural disasters,negligence, terrorism, sccidents or computer hacking, criminal activity and malicious behaviour. When it comes to the ...
European and national assessment procedure for the fire performance of facades
(Proceedings of the 19th International Symposium MASE, Ohrid, 2022, 2022)
Innovative construction systems, increasing use of combustible material in facades, less and less space between buildings, increased energy requirements; the transformation of facades in response to these changes requires ...
Failure analysis of beam of unmanned aerial vehicle
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
The high level of worthiness of unmanned aerial vehicles (UAV), particularly in everyday life, is something that will be common thing in close future. The design solutions for UAV us subject of constant innovation, focused ...
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 ...
