The finite-element model of the system is based on an approximation of the nodal displacements, while the formation of fringes is governed by the stress field in the photo-elastic coating. Without smoothing the reconstructed patterns of the fringes exhibit a non-physical behaviour at inter-element boundaries. When the smoothing parameter is too big, an over-smoothed image isobtained, which may look acceptable but be far from the realistic photo-elastic image. The presented strategy for the selection of the optimum smoothing parameter is generalised for two-dimensional Lagrange finite elements"},{"@xml:lang":"sl","#text":"V prispevku je opisana metoda izbire gladilne spremenljivke. Prikazana je na problemu fotoelastične analize upogibnih nihanj plosče. Model končnih elementov sistema temelji na aproksimaciji pomikov vozlišč, medtem ko na postavitev zunanjih robov vpliva polje napetosti v fotoelastičnem nanosu. Vzorci zunanjih robov, ki smo jih ustvarili brez glajenja, se na mejah med elementi vedejo nenaravno. V primeru, da je gladilna spremenljivka prevelika, dobimo preveč zglajeno sliko, ki sicer lahko izgleda sprejemljivo, vendar je daleč od resnične fotoelastične slike. Predstavljen način izbire optimalne gladilne spremenljivke je posplošen za dvorazsežne Lagrangeve končne elemente"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-XD116WX0","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-XD116WX0"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-XD116WX0/c7e72599-6ae2-4c88-a5d6-3ffe7f309fe8/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-XD116WX0/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-XD116WX0"}}}}
