Microhardness and Macrostructures of Friction Stir Welded T-joints
(Elsevier Science Bv, Amsterdam, 2018)
The results of research regarding the friction stir welding process of T-joints are presented in this paper. Experimental welding of two and three aluminium plates were performed in order to obtain T-joints. Microhardness ...
Numerical simulation of crack propagation in high-strength low-alloyed welded steel
(Elsevier Science Bv, Amsterdam, 2018)
The industrial application of high-strength low-alloyed steel (HSLA) in welded structures has increased the demand for understanding fracture behavior and structural integrity assessment of this type of steel and produced ...
Integrity assessment of ammonia spherical storage tank
(Elsevier Science Bv, Amsterdam, 2018)
The integrity of the ammonia spherical tank (with a volume of 1800 m3 and the outer diameter of 15120 mm, nominal wall thickness 30 mm) was analyzed due to discovered cracks on the longitudinal and transverse but joints ...
Fracture analysis of axially flawed ring-shaped bending specimen
(Elsevier Science Bv, Amsterdam, 2018)
Application of pipelines is common in process industry and energetic facilities, as parts of storage and transport systems. Structural integrity and fracture resistance of the pipeline elements is typically assessed by ...
Structural Integrity Assessment by Using Cross-Correlated Modal Identification
(Elsevier Science Bv, Amsterdam, 2018)
Early researches on steel structures integrity were mainly oriented on calculations and conventional experiments. Robust numerical methods of a high accuracy are usually less reliable in estimation of dynamic properties ...
Damages of burner pipes due to the working conditions and its repair welding
(Elsevier Science Bv, Amsterdam, 2018)
Repair welding represents the activity that restores the working capability of machine or construction caused by some damage due to working or environmental condition. Damages of burner pipes, part of the facility "Cold ...
Crack growth resistance of weldment constituents
(Elsevier Science Bv, Amsterdam, 2018)
The ovennatching can affect the occurrence of cold cracks after welding in high-strength low-alloyed steels of 770 MPa yield strength class. The welding consumable has been designed in a way to produce WM with slightly ...
Geotechnical aspects on seismic retrofit
(Elsevier Science Bv, Amsterdam, 2018)
In the paper numerical analysis of foundation of damaged masonry structure using finite element method is presented. Retrofitting of those structures has been performed using technology DC90. By retrofit design, the ...
Influence of temperature and exploitation time on hardness and micro-structure of a welded joint in a reactor mantle
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents the analysis of the influence of temperature and exploitation time on the cross-sectional hardness and microstructure changes of characteristic zones of a welded joint made of low-alloyed Cr-Mo steel ...
Decreasing bridge member's resistance due to reinforcement corrosion
(Elsevier Science Bv, Amsterdam, 2018)
The traffic infrastructure is very important for the economy, people and progress of the country. The infrastructure consists of numerous structures and their structural members like bridges, abutments, piers, rails, ...
