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 ...
The influence of heat input on the toughness and fracture mechanism of surface weld metal
(Elsevier Science Bv, Amsterdam, 2018)
Surface welding is a way to extend the exploitation life of damaged parts and constructions and the heat input has a major influence on the weldment properties. In this paper is shown the influence of the heat input on the ...
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 ...
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 ...
