“…The wall thickness of valve housing composed of different geometric components has to be calculated in two steps. Galic et al [6] showed that the wall thickness of a two-way globe valve housing in intersection areas, according to [5] is calculated only in the symmetry plane. Finite Element Analysis (FEA) of the part revealed a critical location in the crotch area.…”

“…Nozzle stress results were presented later by Rodabaugh et al [8] but clarification of the stresses in the vicinity of this geometrical continuity continue to be of interest. Other authors also analysed sphere/cylinder junction in their papers [9][10][11][12][13][14] To improve understanding of local conditions in loaded, complex structures, the optical three-dimensional digital image correlation method (DIC) is used in these investigations. DIC methods [15] are non-contacting and can be used for 2D (2D-DIC) and 3D (3D-DIC or StereoDIC) [16] surface displacement and strain measurement (e.g.…”

As pressure equipment is most commonly used in various industrial fields, making manufacturing processes eco-friendlier (e.g. mass reduction of the final product, material and energy savings etc.) and transition to sustainable production by developing eco-innovative products will have positive influence on the environment. The aim of this paper is to analyse globe valve housing exposed to internal pressure using full-field experimental 3D Digital Image Correlation (3D-DIC) method and numerical strain and stress data in order to propose improvements for more sustainable development, with respect to practical engineering application of EN standards. The highest von Mises strain values around 0.03 % were measured on the point of highest geometrical discontinuity, sphere/cylinder intersection. Stresses of the examined globe valve using numerical and theoretical approach are significantly below material yield limit and allowable stress for internal pressure values of 30 bar, that is significantly higher than nominal operating pressure of 6 bar, proving that structure is over dimensioned and can be optimized. New experimental procedure development and application in full-field strain analysis contributes to increased valve housing reliability, mass reduction and material and energy savings during manufacturing which directly affects its eco-friendliness, lowers manufacturing price and increases market competitiveness. Keywords 3D Digital Image Correlation method; Environmental protection; globe valve housing; internal pressure; sustainable development. Highlights • Analytical, numerical and experimental investigation of globe valve is performed. • 3D experimental strain field on sphere/cylinder intersection is measured. • Analysis showed that valve housing is over dimensioned. • Eco-friendliness in globe valve production can be achieved.

Globe valves have widespread application in various industrial sectors. Due to this variety, valve is subjected to different working loads (static, dynamic, thermal etc.) that can cause valve failures. In this paper, the analysis is performed on globe valve subjected to external axial loading caused by pipeline dilatations. Experimental analysis was focused on determining local mechanical properties of critical areas, i.e. on local areas of globe valve housing with high geometrical discontinuities. Experimental analysis and numerical model verification were performed using system Aramis based on Digital Image Correlation method. Using full-field experimental results, numerical model behavior was improved and enabled acquiring more accurate results in transition areas that cannot be found in currently available literature. Determining local mechanical properties of critical areas enables better understanding of complex structures such as valve housing and provides an opportunity for further development and improvement for practical industrial application.

PREDGOVOROvaj rad je nastao nakon višegodišnjeg istraživanja na projektima finansiranim od strane Ministarstva za prosvetu i nauku Republike Srbije, a pre svega tokom rada na projektima "Razvoj savremenih metoda dijagnostike i ispitivanja mašinskih struktura", pod evidencionim brojem TR 35040 i "Razvoj i primena metoda i laboratorijske opreme za ocenjivanje usaglašenosti tehničkih proizvoda" pod evidencionim brojem TR 35031.Pre svega, zahvaljujem se prof. dr Aleksandru Petroviću, mentoru, na nesebičnom zalaganju, podršci, brojnim korisnim savetima i primedbama koji su vešto usmeravali moj naučni rad i uticali na kvalitet ove disertacije. Zahvaljujem se prof. dr Tašku Maneskom na veoma korisnim savetima i podršci koja je u ovoj disertaciji bila od presudnog značaja. Takođe, zahvaljujem se prof. dr Aleksandru Sedmaku, prof. dr Srbislavu Geniću i prof. dr Miloradu Zriliću, koji su doprineli da ova disertacija bude sadržajnija i preglednija.Zahvalnost za stručnu i kolegijalnu pomoć dugujem kolegama Milošu Miloševiću, as.Nikoli Momčiloviću i as. Žarku Miškoviću.Zahvaljujem se svojim roditeljima, Snežani i Radivoju, i svom bratu Nemanji koji su bezrezervno bili tu za mene, na pravi način i u pravo vreme dali vetra u leđa, kada god je trebalo bodrili i podržavali da istrajem do kraja. Mojoj Aleksandri, hvala na ljubavi, strpljenju i pomoći koju je pružala za vreme izrade ove disertacije, njen osmeh i zagrljaj uklanjao je sve poteškoće na ovom putu. AutorNaponi i deformacije struktura kompleksne geometrije cevovodne armature ii NAPONI I DEFORMACIJE STRUKTURA KOMPLEKSNE GEOMETRIJE CEVOVODNE ARMATURE Rezime:Dosadašnja istraživanja u oblasti opreme pod pritiskom, odnosno merenja i određivanja napona i deformacija struktura kompleksne geometrije su se oslanjala na analitičke proračune najčešće bazirane na teoriji ljuski, numeričke proračune upotrebom računarskih softvera i konvencionalne eksperimentalne metode. Kao jedan od najčešćih zaključaka u svojim radovima, istraživači su naveli nepostojanje adekvatnih eksperimentalnih rezultata u postojećoj literaturi, odnosno iskazali potrebu za detaljnom eksperimentalnom analizom kritičnih mesta za koje nije moguće precizno odrediti veličine pomeranja, deformacija ili napona upotrebom analitičkih obrazaca ili numeričkih modela.Ograničenja korišćenih eksperimentalnih metoda su se ogledala u više aspekata. Prvo, za analizu geometrijskih diskontinuiteta, najčešće su korišćene standardizovane epruvete sa pripremljenim diskontinuitetima i ispitivane na zatezanje. Na osnovu dobijenih rezultata su pravljeni dijagrami sa faktorima koncentracije napona, koji su kasnije primenjivani na probleme geometrijski kompleksnih struktura. Ovakav pristup je davao samo okvirna rešenja, koja nisu bila dovoljno precizna i tačna. Drugo, eksperimenti su sprovođeni konvencionalnim metodama. Ograničenje konvencionalnih metoda je lokalno merenje, odnosno dobijanje vrednosti merenih veličina samo u jednoj tački. Treće, merenja su vršena samo u blizini geometrijskih diskontinuiteta, a ne na samim spojevima geom...
