“…The specifications which must be fulfilled for each welded construction are reliability and safety during working. Finite element method (FEM) can be used for numerical analysis of welded joints of under frame wagon structure [1]. The prediction and the multibody dynamic analysis for the fatigue life of the 220t mining truck frame structure and the fatigue life analysis method are presented in [2].…”

“…The methodology applied to identify causes of cracking around the welded joint on the structure of wagon type Sgmns for the transportation of containers and swap bodies is explained in [1]. Because of complicated mounting, bending and welding of underframe structure bottom part, it was not feasible to resolve this matter with a commercial software.…”

The Underframe of Wagon steel structure have both complex geometry and loading conditions producing complex Underframe structure behaviour which is hard to estimate and analyse using the traditional fatigue calculation methods. The impacts of the loading direction, loading type and detail geometrical shapes, i.e. Underframe components which are working in a group, need to be considered carefully in the stress analysis. Using the assumption of elastic behavior for all the underframe structural systems, in which sources of stress increased that have significant effects on the fatigue strength capacity are several included, can over/lower yield stress values to be analyzed in fatigue design. The application of the advanced stress assessment methods in the welding area using the Euro Code calculation studied in this paper produces more accurate stress results that can explain welding crack during operation in The car body of Wagon Steel. Based on Euro Code stress assesment, FEM analysis and measurement can be known that crack on the welding joint of wagon bottom part due to lack finishing of the welding joint. The IIW recommendations can be use in order to repair welding joint finishing to avoid crack fatigue.

Original scientific paper This paper presents the S-N approach to fatigue failure analysis of welded joints that integrates well with finite element modelling. Goodman's criterion and fatigue criterion based on the equivalent stress range were used for the analysis of the fatigue failure. Goodman's criterion and fatigue criterion based on the equivalent stress range, for determining fatigue safety factor are implemented in the software package for finite element analysis PAK. Numerical calculation of fatigue safety factor was determined to assess the integrity of wagon structure parts according to the most commonly used European standards for wagon analysis. According to failure safety factors obtained by Goodman's criterion and fatigue criterion based on the equivalent stress range it should be noticed that both methods give good results. Both criteria give us adequate identification causes of cracking on the underframe of wagon for containers transportation. The obtained results and their well matching prove reliability of both fatigue failure criteria and that they can be used for integrity assessment of wagon structure parts.Keywords: fatigue failure; failure safety factor; FEM; Goodman's criterion Analiza utjecaja izbora kriterija otkaza uslijed zamora na procjenu integriteta vagonske konstrukcije Izvorni znanstveni članak U radu je predstavljen S-N pristup analize otkaza zavarenih spojeva uslijed zamora povezan s metodom konačnih elemenata. Pri analizi otkaza uslijed zamora kriteriji rabljeni za analizu su Goodmanov kriterij i kriterij utemeljen na opsegu efektivnog naprezanja. Goodmanov kriterij i kriterij utemeljen na opsegu efektivnog naprezanja, za određivanje stupnja sigurnosti do otkaza uslijed zamora, implementirani su u softverski paket PAK. Numeričkim proračunima određen je stupanj sigurnosti do otkaza u cilju procjene integriteta dijelova vagonske konstrukcije u skladu s najčešće rabljenim standardima za proračun i analizu vagonskih konstrukcija. Na osnovu izračunatih stupnjeva sigurnosti do otkaza dobivenih Goodmanovim kriterija i kriterija utemeljenih na opsegu efektivnog naprezanja pokazano je da obje metode daju dobre rezultate. Oba kriterija identificiraju prave uzroke pojave pukotina na donjem postolju vagona za prijevoz kontejnera. Dobiveni rezultati i njihovo međusobno dobro poklapanje oba kriterija za određivanje otkaza uslijed zamora nam daju za pravo da se oba kriterija mogu ravnopravno koristiti za procjenu integriteta vagonskih konstrukcija.Ključne riječi: Goodmanov kriterij; MKE ;otkaz uslijed zamora; stupanj sigurnosti do otkaza
