Welding safety by using a new model of welders' recertification in the oil and gas industry
(Institut za ispitivanje materijala, Beograd, 2021)
The paper presents a solution applied for determining the quality of the welding process in oil and gas industrial plants, as well as reliable verification of professional qualification of welding personnel. By applying ...
Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
Assessment of integrity of pressure vessels for compressed air
(Institut za ispitivanje materijala, Beograd, 2021)
Fracture mechanics approach for structural integrity assessment is described in the case of pressure vessels for compressed air. The results of non-destructive testing indicated unacceptable defects on the vessels and set ...
Integrity assessment of ammonia storage tank by non-destructive testing
(Institut za ispitivanje materijala, Beograd, 2021)
Ammonia is a very dangerous fluid, and it is so important that its storage tanks are safe. Fusion welded joints (in further text: welded joints) are the 'weakest' location in some structures, in this case - tanks, and the ...
Structural integrity and life assessment of oil drilling rig pipes using analytical method
(Institut za ispitivanje materijala, Beograd, 2022)
Structural integrity and life assessment of oil rig pipes using analytical method is presented and applied to an oil drilling rig pipe. The new concept based on risk evaluation according to probability and consequence of ...
STRESS CALCULATION AND DEFORMATION OF TANKS LOADED BY INTERNAL GAS PRESSURE LOCATED IN CITY HEATING PLANTS
(Structural Integrity and Life, 2022)
The paper presents the procedure for calculating stress
in gas pressure tanks using finite shell elements for linear
and geometrically nonlinear analysis. Therefore, a procedure has been developed to automatically generate ...
Integrity of Welded Joints Made of Alloy NiCr21Mo
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
The research covers the investigation of mechanical properties of welded joint made on NiCr21Mo alloy (commercial trademark Incoloy 825), and joints of steels P355GH and X2CrNiMo17-12-2, as well as the influence of the ...
Novel procedure to determine actual stress-strain curves
(Institut za ispitivanje materijala, Beograd, 2021)
This paper presents a novel procedure for determining the actual stress- strain curves for undermatching rectangular welded joints made of martensitic armoured steel Armox 500T. The method is based on an analytical expression ...
Technological and economical analysis of curved glass structure
(Belgrade: Society for Structural Integrity and LifeBelgrade: IMS Institute, 2022)
The main concern of this research is to create links and interactive relationship between the design process, materialization and realization of curved glass structure. Based on established typology of curved building ...
Use of digital information in architecture, engineering, construction and operation: standardization efforts
(Belgrade: Society for Structural Integrity and LifeBelgrade: IMS Institute, 2022)
Today, BIM (Building Information Modelling) is the basic technology used to create models and documentation in architecture, engineering, construction and operation (AECO) sector. Although the whole sector is experiencing ...
