Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded joints
(Trans Tech Publications Ltd, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length a ...
Crack tip strain on ship and in situ measurement in shipyards
(IFAC Secretariat, 2007)
The paper presents the application extent of procedures for measurement deformations on ships. The actual deformation distribution was measured on the surface of the specimen by the optical grating method (OGM) parallel ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(Trans Tech Publications Ltd, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
Efficient helium cooling methods for nuclear fusion devices: Status and prospects
(Elsevier Science Sa, Lausanne, 2009)
Helium-cooled reactors offer several important advantages as the helium is an inert and neutron transparent gas. compatible with high outlet temperatures and all structural and functional materials considered for plasma ...

Biomasa u sistemu daljinskog grejanja u Negotinu / Biomass in the district heating system of Negotin
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2007)
Osnovni cilj ove studije je da demonstrira energetske, ekonomske i ekološke koristi supstitucije klasičnih energenata obnovljivim izvorima energije i sistemima centralnog (daljinskog) grejanja. Gotovo 40% teritorije opštine ...
Virtual consultant in welding - Creation of the content server
(Welding in the World, 2007)
In situations where the end users have no domain experts, a virtual consultant in a form of a software surrounding based on updated internet technologies may often show to them the procedure to follow in a given situation ...
Fatigue properties of a high-strength-steel welded joint
(Institute of Metals and Technology, 2007)
In addition to the strength and toughness properties, the fatigue properties of welded joints are necessary for the design of high-strength steel structures exposed to variable loading. Wohler curves were determined for ...
Izrada šavnih cevi od čelika povišene čvrstoće i ispitivanje pokazatelja kvaliteta / Fabrication of high strength seam welded steel tubes and quality indicator testing
(Institut za ispitivanje materijala, Beograd, 2008)
Izbor čelika, dimenzija i načina proizvodnje šavnih cevi je deo procesa konstruisanja, jer je u uskoj vezi sa funkcijom cevi kao konstrukcijske celine u određenim uslovima eksploatacije za predviđeni vek trajanja. Kvalitet ...
