Procena integriteta posuda pod pritiskom sa greškom u zavarenom spoju / Structural integrity assessment of pressure vessels with defect in welded joints
(Vojnotehnički institut, Beograd, 2007)
U radu su prikazani primeri primene parametara mehanike loma za procenu integriteta posuda pod pritiskom sa prslinom. Primena parametara mehanike loma zavisi od niz podataka, pre svega o ponašanju materijala u prisustvu ...
Fracture mechanics and non-destructive testing for structural integrity assessment
(Trans Tech Publications Ltd, Durnten-Zurich, 2009)
Fracture mechanics parameters can be applied for the analysis of failures of structures, and also for prevention of failures when defects in a structure are detected and defined. The approach is presented through stages: ...
Ocena integriteta sfernog rezervoara / Integrity assessment of spherical storage tank
(Institut za ispitivanje materijala, Beograd, 2003)
Analiziran je integritet sfernih rezervoara za amonijak (zapremine 1000 m3, prečnika 12400 mm, debljina zida 30 mm), zato što su otkrivene prsline na liniji stapanja, dužine do 300 mm, različite dubine. Direktnim merenjem ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel
(Institut za ispitivanje materijala, Beograd, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Final stretch zone width determination for MP35N multiphase alloy
(Institut za ispitivanje materijala, Beograd, 2015)
This paper presents an experimental elastic-plastic fracture behaviour analysis in order to evaluate a resistance of the aged and unaged MP35N alloy to stable and unstable crack growth. MP35N fracture behaviour has been ...
Structural integrity assessment from the aspect of fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2019)
An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in ...
Structural Integrity Assessment of Welded Pressure Vessel Produced of HSLA Steel
(Journal Iron Steel Research Editorial Board, Beijing, 2011)
Welded joint is a critical region of a welded structure. The operational safety of welded pressure equipment mostly depends on the behaviour of loaded weldments. Safety of welded structure is dependent on the properties ...
Size/Effect Modeling of Weibull Jc Cumulative Distribution Function Based on a Scalling Approach
(8th International Congress of the Serbian Society of Mechanics, Kragujevac, Serbia, June 28-30, 2021, 2021)
Ever since the 1980s there have been a surge of interest in the size effect, as one of the most
pronounced consequences of fracture mechanics. In the present study, the investigation of the size
effect is focused on ...
Experimental j-integral Determination of Different Weldments Region at Low Temperature
(Proceedings of the 2nd International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2014), 2014)
Behavior of welded joint regions (parent material, weld metal and heat-affected zone) in the presence of crack is presented. Specimens were made of high-strength low-alloy steel and were tested at -40°C. Diagrams load ...
