Sažetak
U okviru ovog rada primenjena je tehnika podmodeliranja na primeru zavarenih ploča u obliku T-spoja, kako bi se proverila osetljivost mreže sa konačnim elementima, kao i da se dobiju preciznije raspodele temperatura, pomeranja i polja zaostalih napona u zavarenom spoju i u njegovoj okolini gde su gradijenti temperature i napona veoma visoki. Procedura submodeliranja procesa zavarivanja prikazana je korak po korak. Dobijeni rezultati raspodele temperature, zaostalih napona i pomeranja veoma dobro se slažu sa eksperimentalnim merenjima i analitičkim rešenjima iz literature.
