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 ...
XRF and LIBS measuring on metal and ceramic laser-cleaned surfaces
(IMEKO-International Measurement Federation Secretariat, 2016)
The use of lasers in the conservation of artefacts plays an important role since its posibilities of safe, efficient and efective cleaning on complex surfaces and wide range of materials. This paper presents the results ...
Complexity of Curved Glass Structures
(IOP Publishing Ltd, Bristol, 2017)
Despite the increasing number of research on the architectural structures of curvilinear forms and technological and practical improvement of the glass production observed over recent years, there is still a lack of ...
Creep crack growth - Comparison of two steel P91 and P22
(International Conference on Fracture, 2017)
The deformation and crack growth behaviour of P22 and P91 steel weldments tested at 550 °C and 600 °C, respectively,compact C(T) type specimens with sharp EDM starter notches in the base metal (BM) and heat affected zone ...
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 ...
Measuring of Strain and Displacements in Welded Joints Subjected to Tensile Load Using Stereometric Methods
(Springer-Verlag Berlin, Berlin, 2017)
During the experimental testing of a welded joint, made of steel P460NL1, complete strain and displacement fields, which provide full insight into the behaviour of a welded joint under tensile load, were obtained using an ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(International Conference on Fracture, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
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 ...
Temperature and time effects on fracture toughness values in welded joint
(International Conference on Fracture, 2017)
Temperature and time effects on fracture toughness have been investigated for characteristic regions in a welded joint made of Cr-Mo steel A-387 Gr. B. Comparative analysis of fracture toughness values for characteristic ...
