Glass façade specimens consist of three basic components: hardened glass, polysulfide or silicone adhesive and a polymer profile. Each component has its own specific acoustic impedance, which relates to a difference in the ultrasound reflection and transmission coefficients. Several glass façade specimens containing defects like air pockets, grease and duct tape are analysed. Measurements are carried out using a normal incidence piezoelectric transducer. Experiments are performed on several adhesively bonded joints in order to detect the defects in the glass-adhesive and adhesive-polymer profile interfaces. Most of the defects, except smaller areas of grease, can be successfully detected. The experimental results suggest that pulse-echo ultrasonic testing is a reasonable way of evaluating of adhesively bonded joints in glass façades"},{"@xml:lang":"sl","#text":"Namen raziskav je razviti možen način ocenjevanja kakovosti lepljenih spojev v steklenih fasadah. Izbrana metoda preiskav naj bo neporušna, enostavna za uporabo in cenovno ugodna. Z razvojem gradbeništva in industrije so se povečale možnosti uporabe steklenih panelov v fasadah različnih stavb. Za zagotavljanje kakovosti lepljenih spojev steklenih panelov je treba le te testirati v proizvodnji in tudi med uporabo, saj lahko slabo lepljeni spoji predstavljajo nevarnost za ljudi in okolico. Lepljene spoje lahko pregledujemo vizualno, vendar nam to običajno ne nudi celovite slike o kakovosti spoja, še posebej pri neprozornih materialih. Za preiskavo te vrste materialov lahko uporabimo ultrazvočne preiskave"}],"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-8UKSBNWD","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-8UKSBNWD"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-8UKSBNWD/6305b6b5-58f1-4d3a-b6ad-97492368c2cf/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-8UKSBNWD/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-8UKSBNWD"}}}}
