U ovome radu istražuju se groteskni elementi u dramama Mate Matišića i Ive Brešana. Odabrane drame (Anđeli Babilona, Svećenikova djeca; Hidrocentrala u Suhom dolu, Viđenje Isusa Krista u kasarni V.P. 2507) suvremene su hrvatske drame, zbog čega će u prvom dijelu rada biti izdvojene različite teorije groteske, zatim ponešto o poimanju groteske u umjetnosti, posebice u suvremenoj hrvatskoj drami šezdesetih (na kazališnoj sceni) i sedamdesetih (u pisanoj drami) godina dvadesetoga stoljeća te njihovu poveznicu. Uz navedeno, neizostavni, a ujedno i temeljni dio rada su i primjeri grotesknih elemenata (grotesknih situacija, likova, jezika) na temelju kojih se mogu zamijetiti sličnosti i razlike pri korištenju groteske kod Matišića i Brešana. Dok kod Brešana groteska proizlazi iz spoja tragičnoga i komičnog (pri čemu je nerijetko teško razlučiti jedne i druge elemente), karnevalizacije te karikaturalnosti i izobličenja, u Matišićevim dramama elementi komike postupno prelaze u groteskno. Međutim, različiti načini ostvarenja grotesknoga kod ove dvojice autora ipak dovode do jednakog rezultata, prožimanja njihovih drama grotesknim elementima zahvaljujući kojima se dodatno pojašnjavaju situacije koje se mogu zamijetiti i u svakodnevnom životu, ali su u djelima ipak ispunjena izobličenjima i karikaturalnošću. In this work are exploring grotesque elements in the plays of Mate Matišić and Ivo Brešan. Selected dramas (Angels of Babylon, Priest's children, Hydroelectric power station in Suhi dol, Vision of Jesus Christ in barrack V. P. 2507) are modern Croatian dramas and because of that fact in the first part of work will be presented various theories of grotesque, than something about the notion of grotesque in art, especially in modern Croatian drama in 1960s (at the theatre scene) and 1970s (in written drama), as well as their connection. Beside mentioned, indispensable and at the same time fundamental parts of this paper are examples of grotesque elements (grotesque situations, characters, language) on the bases of which we can notice similarities and differences in the use of grotesque by Matišić and Brešan. While in Brešan's work grotesque is a result of compound of tragic and comical (when you consider the fact that is difficult to distinguish between one and the other elements), carnivalization, caricatural elements and distortions, in Matišić's dramas elements of comedy gradually exceed into the grotesque. However, different ways of achieving grotesque by these two authors lead to the same result, pervasion their plays with grotesque elements (characters, situation, language), thanks to which situations that can be noticed in everyday life are additionally clarified, but in the dramas they are filled with distortions and caricatural elements.

Proizvodnja alata za tlačno lijevanje aluminija skupocjen je i dugotrajan proizvodni proces, te je samim time i cijena proizvedenih alata visoka. Pred alatničarima je izazov da alate za tlačni lijev izrađuju točno, brzo i bez većih dorada. Svakom doradom se povećavaju troškovi izrade, a to smanjuje konkurentnost i ugrožava opstanak na zahtjevnom tržištu. Najviše vremena i potrošenih sredstava odlazi na proizvodnju matrica alata. Alati se proizvode konvencionalnim i nekonvencionalnim proizvodnim tehnologijama, te se često pristupa manje rizičnim, ali i skupljim, provjerenim metodama obrade . Komponente alata za tlačno lijevanje aluminija moraju imati povećanu tvrdoću da bi im se smanjilo trošenje uzrokovano visokim temperaturama lijevanja prilikom eksploatacije pa se zato toplinski obrađuju na zahtijevanu tvrdoću. U ovom radu opisane su proizvodne tehnologije koje se javljaju pri izradi alata za tlačno lijevanje aluminija na primjeru jedne alatnice, te koji su sve utjecajni parametri krajnje kvalitete i točnosti komponenata, a samim time i aluminijskog odljevka. Prikazan je tehnološki postupak izrade matrica, te su opisani dodaci materijala koji se ostavljaju za toplinsku i završnu obradu. Dodaci materijala na matricama, toplinske deformacije i završno obrađene matrice su analizirani na modelima dobivenima metodom 3D skeniranja. U završnom dijelu predloženo je poboljšanje procesa na temelju podataka dobivenih pri analizi skenova tri različite matrice. Production of tools for die casting of aluminium is an expensive and a long manufacturing process, which in effect carries the high price of the tool. Toolmakers are challenged to manufacture tools for die casting with great precision, in shorter manufacturing times and without greater required finishing. With every extra finishing the manufacturing cost rises, lowering competitiveness and the chance of survival in a challenging market. Most time and resources are used on manufacturing of tool dies. Tools are manufactured using conventional and unconventional manufacturing technologies, and usually the more familiar, but more expensive machining methods are used which carry less risk. Die cast tooling components are required to have increased hardness to reduce tool wear caused by exploitation in high temperature casting environment so therefore they go through heat treatment to gain required hardness. In this thesis manufacturing methods which are required to manufacture a tool are described by the example of one toolshop, and which are the influential parameters of end quality and precision of components, and thus that from an aluminium casting. The technological process of die making is explained, and the material allowances required for later heat treatment and finishing. Die material allowances, thermal deformations and finished dies were analysed on the models obtained by 3D scanning method. In the last part of the thesis process improvement is proposed based on the data obtained by analyzing scans of three different dies.

U ovom diplomskom radu ispitivan je utjecaj brzine zavarivanja na deformacije prilikom zavarivanja raznorodnih čelika (konstrukcijskog čelika i nehrđajućeg čelika). U početnom, teorijskom dijelu ovog diplomskog rada obrađena je primjena numeričkih simulacija u zavarivanju, s naglaskom na aplikaciju 'Visual-Weld', nakon čega je obrađen MIG/MAG postupak zavarivanja koji će biti korišten prilikom eksperimentalnog dijela rada. Potom je obrađena zavarljivost raznorodnih čelika i na samom kraju ovog teorijskog dijela analizirani su načini za smanjenje deformacija i zaostalih naprezanja u zavarenim konstrukcijama. U eksperimentalnom dijelu rada zavaren je sučeljeni spoj dvaju raznorodnih čelika, kako bi se ispitao utjecaj brzine zavarivanja na deformacije, a potom je provedena i simulacija zavarivanja u programu 'Visual-Weld' kako bi se utvrdila usporedivost rezultata dobivenih simulacijom i zavarivanjem. In this graduate thesis the task was to examine the influence of welding velocity on distortions during welding of dissimilar steels (structural steel and stainless steel). First, theoretical part of this thesis deals with the application of numerical simulations in welding, with emphasis on the program called ‘Visual-Weld’, and after that the MIG/MAG welding process was briefly described because MAG process will be used in experimental part. Afterwards, the weldability of dissimilar steels was also described and at the end of this theoretical part, mechanisms for residual stresses and distortions reduction have been also analyzed. In the experimental part of this thesis, the joint of dissimilar steels has been welded in order to examine the influence of welding velocity on distortion, and after that the welding simulation in 'Visual-Weld' was carried out to determine the comparability of results obtained by simulation and welding.

U ovom radu obrađena je primjena numeričkih simulacija koje se koriste pri zavarivanju zavarenih konstrukcija. Obrađena je i zavarljivost austenitnih nehrđajućih čelika. Objašnjen je mehanizam nastajanja trajnih deformacija i zaostalih naprezanja zavarenih spojeva, te faktori koji utječu na njihovu pojavu. Zatim su analizirani mehanizmi smanjenja zaostalih naprezanja i deformacija u zavarenim konstrukcijama. Na kraju teorijskog dijela navedene su neke komercijalne aplikacije za simulaciju procesa zavarivanja te su opisane njihove mogućnosti. U eksperimentalnom dijelu rada izrađeni su T-spojevi limova od nehrđajućih čelika impulsnim MIG postupkom zavarivanja. Zavarena su dva uzorka, različitim parametrima zavarivanja te je analiziran utjecaj parametara na veličinu kute deformacije. Nakon izrade uzoraka, izvršena je simulacija zavarivanja u programu Visual Weld 11.0, kojom se nastojalo replicirati zavarivanje uzoraka. Napravljena je usporedba rezultata simulacije i stvarnih deformacija te su donešeni zaključci o primjenjivosti programske aplikacije Visual Weld za realne proizvode. The subject of this thesis is the application of numerical simulations used in welding industry. Weldability of austenitic stainless steels is also described. The mechanism of forming of permanent deformation and residual stress of welded joints, along with the factors that influence their occurrence are described. Also, mechanisms of reduction of residual stress and deformation in welded joints are analyzed. Furthermore, commercial applications of welding simulation software and their capabilities are discussed. For the experimental part of the thesis, stainless steel T-joint welds were made using MIG pulsed welding method. Two specimens were welded using different welding parameters and the effect of welding parameters on the magnitude of angular distortion was analyzed. After the specimens were made, simulation of the welding process was carried out using Visual Weld 11.0 software with the objective of trying to replicate the results of welding the specimens. The comparison of simulation results and real deformations was carried out on the basis of which the conclusions were made about the applicability of Visual Weld 11.0 simulation software in real life applications.

U radu se daje odgovor na pitanje: koja je najbolja Lambertova konformna konusna projekcija za Hrvatsku ako se u područje preslikavanja uključi i morski dio Hrvatske (teritorijalno more i epikontinentalni pojas)? Numerička realizacija rada zahtijevala je koordinate najsjevernije i najjužnije točke Hrvatske, kako na kopnu tako i na moru. Utvrđeno je da koordinate najjužnije točke Hrvatske na moru, tj. one na crti epikontinentalnog pojasa nisu dosad točno izračunane, pa je to trebalo napraviti. Zatim je analizirano osam varijanti konformnih konusnih projekcija s obzirom na raspored linearnih deformacija. Svaka je varijanta jasno definirana, a one se međusobno razlikuju po konstantama projekcije koje su dobivene na temelju postavljenih početnih uvjeta. Na temelju provedenih istraživanja predložena je najbolja Lambertova konformna projekcija za područje Hrvatske uključujući njezino teritorijalno more i epikontinentalni pojas., The paper gives an answer to the question: if the maritime area of Croatia (territorial sea and continental shelf) is involved, which is the best Lambert conic conformal map projection for the territory of Croatia? Numerical realization demanded the northernmost and the southernmost coordinates on the land and sea of Croatia. Since the coordinates of the southernmost point on the sea, i.e. those on the line of the continental shelf, had never been calculated before, it had to be done in this work. Thereafter eight variants of conic conformal map projections with respect to the distribution of linear distortions were analyzed. Each variant was clearly defined, and they differ in the constants of projection which were obtained by setting initial conditions. On the basis of performed research the best Lambert conic conformal map projection for the territory of Croatia including its territorial sea and continental shelf was proposed.
