Aplication of Metal Matrix Composite Coatings in Thermal Power Plants
(4th Conference of the Serbian Society for Ceramic Materials, Programme and the book of abstracts, 2017)
Nanomaterials for sustainable energy production and storage: Present day applications and possible developments
(Springer International Publishing, 2017)
Currently used technologies in energy industry are oftentimes potentially harmful for the environment and/or not sustainable in the long run (e.g. fossil and mineral based fuels, nuclear energy). Therefore the oncoming ...
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 ...
CFD Calculation of Helicopter Tail Rotor Airloads for Fatigue Strength Experiments
(Asce-Amer Soc Civil Engineers, Reston, 2017)
This work focuses on defining loads and fatigue life estimation of helicopter tail rotor blades. The original metal construction of these blades was replaced with a new construction of blades made from composite materials. ...
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 ...
Numerical simulation of fatigue crack growth in welded pipes
(International Conference on Fracture, 2017)
Numerical simulation of fatigue crack growth has been performed by using the extended finite element method (xFEM) for modeling fatigue crack growth in a pipe made of API j55 steel by high-frequency welding. The obtained ...
Fracture mechanics in Serbia - 49 years of development
(International Conference on Fracture, 2017)
Development of fracture mechanics in Serbia has been presented. To start with, it was the Magister thesis of Prof. Stojan Sedmak, 49 years ago (1968), as the first milestone. The stress concentration problems have been ...
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, ...
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 ...
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 ...
