Effect of vibration on the variation of residual stresses and impact energy in butt-welded joints / Uticaj vibracija na promenu zaostalih napona i energije udara kod sučeono zavarenih spojeva
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a ...
Applicability of risk-based maintenance strategy to a penstock / Strategija održavanja zasnovana na riziku - primenljivost na cevovod
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The risk of brittle fracture of the penstock of the reversible pump turbine is recognized in an early stage of design. To reduce the cost of penstock construction one tunnel is accepted. The HSLA steel of 700 MPa yield ...
Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters / Procena ponašanja zavarenog spoja HSLA čelika opterećenog na zamor primenom parametara mehanike loma
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
From a fracture mechanics point of view on welded joints, it is assumed that the welded joint is pre-cracked such as that the fatigue life of the pre-cracked structure is then determined by the period of crack growth under ...
Leakage of an austenitic steel CO2 storage tank / Curenje posude za skladištenje CO2 od austenitnog čelika
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
After the occurrence of water droplets on the manhole outer wall of a storage tank for carbon dioxide, by detailed inspection, a net of cracks is detected in the manhole flange, close to the welded joint between the flange ...
Significance and applicability of structural integrity assessment / Značaj i primenljivost ocene integriteta konstrukcija
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
To avoid unexpected and frequent serious failures of objects and equipment in service, and save their structural integrity, proper experimental and theoretical analyses are required, that are supported by modeling and ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 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 ...
Quality assurance of storage tanks after in-service crack repairs / Osiguranje kvaliteta rezervoara u eksploataciji posle popravke prslina
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
According to the Pressure Equipment Directive (PED 97/23/EC) a new produced storage tank can be accepted on the market only if the required quality is proved. In this way the structural integrity might be at the requested ...
Assessment of pressure vessel load capacity in the presence of cracks / Procena nosivosti posude pod pritiskom u prisustvu prsline
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
The paper illustrates the structural assessment of an investigated pressure vessel, made of low-alloyed high strength steel, with an external surface crack located on the shell wall. In order to assess the remaining strength ...
Strength design calculation of a horizontal pressure vessel / Kontrolni proračun čvrstoće horizontalne posude pod pritiskom
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
Standards SRPS M.E2.250-262 for calculation of pres-sure vessels have been replaced by SRPS EN 13445-3. This means that calculations of new equipment and check calculations of equipment in service are subjected to ordinance ...
Influence of working conditions on strength calculation of pressure vessel of austenitic steel according to SRPS EN 13445 / Uticaj radnih uslova na proračun čvrstoće posude pod pritiskom od austenitnog čelika prema SRPS EN 13445
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
Upon the adoption of regulations for pressure equipment the series of standards SRPS EN 13445 began to apply. The paper illustrates strength calculation of a vertical cylindrical pressure vessel of austenitic steels according ...
