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 ...
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 ...
Structural integrity of butt welded connection after fire exposure
(Elsevier Science Bv, Amsterdam, 2018)
The paper presents a study for fire behavior of the butt-welded joints subjected to low cycle fatigue loading, taken into account the post fire conditions and the possibility of welding strengthening. The need of in service ...
Effects of welding technology on the occurrence of fracture in welded joints
(Elsevier Science Bv, Amsterdam, 2018)
Welded joints represent locations where failure is most likely to occur in welded structures. Welded joint failure depends on their vulnerability to crack initiation and growth. These factors are significantly influenced ...
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, ...
Strain measurement of pressure equipment components using 3D Digital Image Correlation method
(Elsevier Science Bv, Amsterdam, 2018)
Pressure equipment has widespread application in various industrial sectors. Due to this variety, pressure equipment can have complex structure and is subjected to different working loads (static, dynamic, thermal etc.) ...
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 ...
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 ...
