Butt welded joints assessment after fire exposure
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The need of in service life of a steel structure after being exposed to fire raises the problem of strengthening or replacement of some structural elements. In many cases, after structural safety assessment, fire exposed ...
Effect of laser beam welded reinforcement on integral skin panel fatigue life
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, numerical analyses of fatigue crack growth in integral skin-stringer panel produced by means of laser beam welding (LBW) are presented along with fatigue results verified by previously conducted experiments. ...
Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
Influence of welded joint microstructures on fatigue behaviour of specimens with a notch in the heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, the results of determining the Paris law coefficients, C and m, are presented, based on the experimental data obtained by three-point bending testing of 8 welded joint specimens. The specimens were taken ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Determining the crack acceptability in the welded joints of a wind loaded cylindrical steel shell structure
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Engineering critical assessment can be considered as a mandatory request in the civil engineering designing and manufacturing process. The paper is presenting the procedure for determination of crack acceptability based ...
The renewed TC12/ESIS technical committee - Risk analysis and safety of large structures and components
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The ESIS Executive Committee decided to nominate a new team for the leadership and management of the TC12/ESIS technical committee (TC), as well as update the TC name as "Risk Analysis and Safety of Large Structures and ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
