Limit load solution for mismatched welded plate and pressure vessel with a surface crack

Autor: Argoub Emhamed, Sedmak Aleksandar, Sedmak Stojan, Adziev Gorgi

Publikováno v: Theoretical and Applied Mechanics, Vol 32, Iss 2, Pp 97-112 (2005)

Fracture behavior of a structure having a crack in the middle of a weld is influenced by the mechanical properties of the welded joint constituents (weld metal, base metal, heat-affected-zone) and their geometry. Therefore, defect assessment procedur

Quality assurance of storage tanks after in-service crack repairs

Autor: Bakić, Ramo, Milović, Ljubica, Jovičić, Radomir, Sedmak, Stojan

Publikováno v: Integritet i vek konstrukcija

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 level. However, it is not po

Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters

Autor: Milović, Ljubica, Bulatović, Srđan, Aleksić, Vujadin, Radaković, Zoran, Marković, Svetislav, Sedmak, Stojan

Publikováno v: Integritet i vek konstrukcija

U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. Eksperimentalni podaci dobije

Applicability of risk-based maintenance strategy to a penstock

Autor: Sedmak, Tamara, Bakić, Ramo, Sedmak, Stojan, Milović, Ljubica, Kirin, Snežana

Publikováno v: Integritet i vek konstrukcija

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 stress, 47 mm thick, is selecte

Leakage of an austenitic steel CO2 storage tank

Autor: Jovičić, Radomir, Sedmak, Aleksandar, Sedmak, Stojan, Milović, Ljubica, Jovičić, Katarina

Publikováno v: Integritet i vek konstrukcija

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 and manhole mantle. Since t

Chronology of lost structural integrity initiated from manufacturing defects in welded structures

Autor: Sedmak, Stojan, Grabulov, Vencislav, Momčilović, Dejan

Publikováno v: Integritet i vek konstrukcija

U različitim vremenskim periodima dolazilo je do gubitka integriteta zavarenih konstrukcija zbog razvoja proizvodnih grešaka zavarenog spoja. Mehanizmi otkaza su bili različiti i uvek su predstavljali novo iskustvo, koje je zahtevalo nova znanja i

Toughness and ductility of high strength steels welded joints

Autor: Grabulov, Vencislav, Blačić, Ivo, Radović, Aleksandar, Sedmak, Stojan

Publikováno v: Integritet i vek konstrukcija

Tri metode ispitivanja različitim brzinama opterećenja epruveta sa zarezom (udarno klatno, padajući teg, izbočavanje eksplozijom) su primenjene za ocenu žilavosti i duktilnosti ručno elektrolučno zavarivanih spojeva. Osnovne osobine zavarenih
