Size/Effect Modeling of Weibull Jc Cumulative Distribution Function Based on a Scalling Approach
(8th International Congress of the Serbian Society of Mechanics, Kragujevac, Serbia, June 28-30, 2021, 2021)
Ever since the 1980s there have been a surge of interest in the size effect, as one of the most
pronounced consequences of fracture mechanics. In the present study, the investigation of the size
effect is focused on ...
Corrigendum to “A scaling approach to size effect modeling of Jc CDF for 20MnMoNi55 reactor steel in transition temperature region”
(Engineering Failure Analysis, 2022)
The influence of the temperature and exploitation time on the behaviour of a welded joint subjected to variable and impact load
(International Conference on New Trends in Fatigue and Fracture, 2018)
This paper presents the analysis of the temperature and exploitation time influence on the resistant measure to brittle fracture of welded joint constituents of the new and exploited low-alloyed Cr-Mo steel A-387 Gr. B ...
The Effects of Exploitation Conditions and Welding on Crack Initiation and Propagation in a Starting Pressure Vessel
(International Conference on New Trends in Fatigue and Fracture, 2018)
Cracks and other defects that can occur in pressure vessel have been a significant practical problem for the integrity of such vessels for a very long time, and these defects can initiate and propagate due to various ...
Numerical simulation of the influence of reinforcement ring on the stress and strain distibution in pressure vessels
(International conference on structural integrity and durability 2017, ICSID 2017, Book of abstracts, 2018)
The analysis of the influence of a reinforcement ring on the stress and strain state within a pressure vessel by using numerical methods is presented in this paper. The aim was to compare the numerical results for different ...
Influence of exploitation conditions and welding on crack initiation and propagation in pressure vessels
(The Third International Conference on FRACTURE MECHANICS "Engineering Applied Fracture Mechanics and Environment", 2016)
Cracks in pressure vessels represent considerable and serious practical prob-lem. These defects can be initiated and enhanced by various factors, such as manufacturing processes, development technology, welding, working ...
Increased hydraulic resistance in tubes of once-through boiler due to fouling: a case study of 650 MWe ligite fired unit
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2022)
The analysis of pressure changes in water and steam flow along the entire once-through steam
boiler tube system at the 650 MWe lignite fired Unit was carried out after the long operational period
of almost 30 years ...
Repair Welding Of Lower Rails Of A 30CrMoV9 Steel Transport Beam And The Conditions Under Which The Welding Procedure Must Be Carried Out
(Proceedings of the 5th International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2017), 2017)
Welding technology used for repairing of the lower rail of a 30CrMoV9 steel transport beam is
presented in this paper. Following the previously performed repair welding, a large number of
cracks were detected, located ...
Reparation, inspection and damage analysis of steam boiler
(Welding & Material Testing, 2020)
Problem that is not very common but very dangerous for steam boilers is the furnace tube failure during exploitation and usually that caused by some defects base material or exploitation condition. In this particular case, ...
Effect of DIC equipment calibration on deformation measuring errors
(2015)
Shown in this paper is the application of stereometric deformation measuring method on a welded
joint made of steel P460NL1, along with its drawbacks. Stereometric measuring of deformation is a technique with a wide ...
