Thermal history and stress state of a fresh steam-pipeline influencing its remaining service life
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
The service life of thick-walled power plant components exposed to creep, as is the case with pipelines of fresh- and reheated steam, depend on the exhaustion rate of the material. Plant operation at elevated temperatures ...
Rectified ethanol production cost analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, ...
Numerical study of transient three-dimensional heat conduction problem with a moving heat source
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
A numerical study of transient three-dimensional heat conduction problem with a moving source is presented. For numerical solution Douglas-Gunn alternating direction implicit method is applied and for the moving heat source ...
Tribological Aspects and Energy Consumption in Ballroom Dance as a Human Activity
(Proceedings of 3rd European Conference on Tribology „Viennano ’11“, 2011)
Analiza rizika integriteta konstrukcija / Risk analysis in structural integrity
(Institut za ispitivanje materijala, Beograd, 2011)
Risk analysis has been presented, as the new approach for solving problems in structural integrity assessment. The inspection concepts have been described, based on risk (RBI) and reliability (RCM), focused on companies ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
Thermal stress analysis of a fiber-epoxy composite material
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
Paper presents stress calculation in the stationary temperature domain for a hybrid structure with standard epoxy-carbon fiber composite and metallic part, showing different thermal behavior. The thermal stress analysis ...
