Influence of the Process Input Parameters on the Cross-Wire Weld Breaking Force
Cross-wire welding is a type of electric resistance welding called projection welding that is used in the production of a variety of products. This paper deals with the case where steel wires of equal radii are joined together to form a reinforced steel mesh. The objective of the study is to determine the correlation between the welding parameters and the breaking force of the weld. Each weld is cut out from the given wire mesh and tested separately by destructive testing on the universal testing machine. A modular testing fixture was constructed for the tests. Although the tests are still in the initial stage, the results already give a good insight into the influence of the process input parameters on the breaking strength of the weld
Diplomatic relations between Vatican State City and Kingdom of Yugoslavia: the concordat of 1935.
Autori analiziraju politiÄka i vjerska previranja iz prve polovice 20. stoljeÄa izmeÄu Kraljevine Jugoslavije1 i Vatikana, tijekom desetljeÄa politiÄkih odnosa, od samoga poÄetka Kraljevine do Drugoga svjetskog rata. Poseban naglasak stavljen je na dogaÄaje vezane uz potpisivanja konkordata u srpnju 1935. te njegovim posljedicama. Prikazana je reakcija s hrvatske i srpske strane. Predstavljena je politiÄka situacija Kraljevine Jugoslavije te razmirice koje su proizlazile izmeÄu hrvatske i srpske (katoliÄke i pravoslavne) strane.The thesis will depict political and religious turmoil from the first half of the 20th century between Kingdom of Yugoslavia45 and Vatican State City, and present more than a decade of political relations, from the Kingdomās very beginning up to World War II. Special emphasis will be on the events that occurred during the signing of the concordat in July 1935 and its consequences. The thesis will be concluded with reactions from both Croatian and Serbian side. This will present the entire political background in Kingdom of Yugoslavia and the disputes between Croatian and Serbian (Catholic and Orthodox) politicians

Idejni projekt ceste izvodi se na zadanoj geodetskoj podlozi u mjerilu 1 : 1000 koja prikazuje teren na kojoj se cesta projektira. Cesta se formira od toÄke A koja se nalazi na 319 metara nadmorske visine prema toÄki B koja se nalazi 299 metara nadmorske visine. Vrsta terena na kojem se polaže trasa je brdoviti. Cesta se projektira za prosjeÄni godiÅ”nji dnevni promet koji iznosi 950 vozila/dan (PGDP). PredviÄena projektna brzina je 40 km/h. Trasa kontinuirane ceste ima dužinu 318,69 m. Idejno rjeÅ”enje izraÄeno je prema Pravilniku i osnovnim uvjetima za projektiranje ceste s elementima koji zadovoljavaju važeÄe propise, kao i sigurnosne i estetske kriterije.The preliminary design of the road is performed on a given geodetic base at a scale of 1 :1000, which shows the terrain on which the road is designed. The road is formed from point A located at 319 meters above sea level towards point B, which is located at 299 meters above sea level. The type of terrain on which the route is laid is hilly. The road is designed for an average annual daily traffic of 950 vehicles / day (PGDP). Estimated design speed is 40 km / h. The route of the continuous road has a length of 318,69 m. The conceptual design was made according to the Ordinance and the basic conditions for the design of roads with elements that meet the applicable regulations, as well as safety and aesthetic criteria
NumeriÄko modeliranje mehaniÄkog ponaÅ”anja nanokompozitnih struktura : doktorska disertacija
U ovom je radu predstavljeno numeriÄko modeliranje mehaniÄkog ponaÅ”anja
nanokompozitnih materijala, zasnovano na raÄunalnoj homogenizaciji kao viÅ”erazinskoj
metodi modeliranja. Kao uvod, dana je kratka povijest nanomaterijala i teorijska
pozadina o ugljiÄnim nanocijevima i numeriÄkom modeliranju istih. TakoÄer, dana je
teorija o kompozitnim materijalima, buduÄi se na teoriji kompozita zasniva i teorija
nanokompozitnih materijala. Posebna pozornost obraÄena je meÄudjelovanju izmeÄu
osnovne matrice nanokompozitnog materijala i ugljiÄne nanocijevi kao poboljÅ”anja te je
predstavljen naÄin numeriÄkog modeliranja takvih meÄudjelovanja koji se najveÄim
djelom zasnivaju na slabim van der Waals vezama. U svrhu analize tih meÄudjelovanja
razvijen je i poseban program, koji na osnovu zadanih parametara omoguÄuje
modeliranje veze izmeÄu matrice nanokompozita i nanocijevi ili izmeÄu dva razliÄita
sloja unutar viÅ”estrukih ugljiÄnih nanocijevi. Problem modeliranja nanokompozitnih
struktura je viÅ”erazinski problem, stoga je dio rada posveÄen viÅ”erazinskim metodama,
gdje je veÄa pažnja posveÄena raÄunalnoj homogenizaciji prvog reda. Upravo je na
raÄunalnoj homogenizaciji prvog reda i upotrebi reprezentativnog volumnog elementa
baziran program za numeriÄko modeliranje nanokompozita. U svrhu verifikacije
programa, dana su 4 modela nanokompozitnih materijala, razliÄitih karakteristika, a
dobiveni rezultati usporeÄeni su s rezultatima drugih autora.A method for the numerical modelling of mechanical behaviour of nanocomposite
materials, which is based on computational homogenization as a multiscale method, is
presented in this work. As an introduction, a brief history of the nanomaterials and
theoretical background about the carbon nanotubes and numerical modelling of the
carbon nanotubes is presented. Also, the theory about composite materials is given, since
it is also the basis of the nanocomposite materials theory. A special attention is devoted to
the nanocomposite matrix and reinforcement interaction. A method of numerical
modelling of those interactions, which are mainly based on the weak van der Waals
forces, is presented. An algorithm is developed for analysis of those interactions, which
enables modelling of bonds between nanocomposite matrix and nanotubes or between
two different layers of multiwalled carbon nanotubes, based on input parameters. Since
the problem of modeling nanocomposite structures is a multiscale problem, one part of
this work is dedicated to multiscale modeling methods, especially to the first order
computational homogenization. Computational homogenization and representative
volume element are the basis of the presented software for numerical modelling of the
nanocomposites. For the purpose of the software verification, 4 models of the
nanocomposite material, with different characteristics, are presented. Obtained results are
compared with the results from the other authors
