Finite element model for stress state analysis of deep groove ball bearings with defects
(Proceedings of the 5th International Scientific Conference, ”Conference on Mechanical Engineering Technologies and Applications” COMETa2020, East Sarajevo, 2020)
In the framework of Industry 4.0, new specific or improved methods for
monitoring and prediction of operational conditions of machine elements are required.
Ball bearings are among the elements with high impact on safety ...
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 ...
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 ...
Geometric optimization of transition zones based on biomimetics principles
(Journal of the Serbian Society for Computational Mechanics, 2021)
The basic definitions and a history of the development of biomimetics as a discipline that
considers nature-inspired design are presented in this paper. The discussion and the results of the
application of principles of ...
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 ...
