Abstract
Tema ovog završnog rada je analiza naprezanja i deformacija u toplinski opterećenoj konstrukciji. Prije same analize, koja se temelji na principima metode konačnih elemenata kratko je opisana zadana konstrukcija, te mehanička i toplinska svojstva materijala deformabilnih ploča korištenih u sklopu. Numerička analiza izvodi se u programskom paketu ABAQUS, te je stoga u ovome radu dan kratak osvrt na teorijsku podlogu navedenog programskog paketa. Također, opisani su korišteni trodimenzionalni elementi koji su korišteni u numeričkoj analizi. U analizi se koriste osnovni heksaedarski „brick“ elementi za toplinska i mehanička opterećenja, te superponirani elementi za termomehaničke primjene. Prije početka numeričke analize zadane konstrukcije, odabrani elementi su verificirani na poznatim problemima koje je uz određena pojednostavljenja moguće riješiti analitičkim putem. Numerička analiza rađena je za tri različita tipa toplinskog opterećenja, te su za svaki tip opterećenja opisani rubni uvjeti, stacionarnost ili tranzijentnost problema, te proces dobivanja konačne diskretizacije proračunskog modela analizom konvergencije. Nakon provođenja analize detaljnije su opisani dobiveni rezultati, te prikazane karakteristične raspodjele pomaka, naprezanja i temperatura.
Abstract (english)
The subject of this final paper is analysis of stresses and strains in construction subjected to thermal load. Before the analysis, which is based on the principles of finite element method, a short description of given structure is provided, and mechanical and thermal properties of deformable plates used in assembly is given. Numerical analysis is carried out in software package called ABAQUS, so in this paper it is given a short overview of theoretical basis of specified software package. Finite elements used in numerical analyisis are also described. The analysis used basic three-dimensional hexahedron „brick“ elements for thermal and mechanical loads, and superimposed elements for thermomechanical applications. Before the numerical analysis of given construction, chosen elements are verified on known problems, which can be analytically solved with certain simplifications. Numerical analysis is done fore three different types of thermal load, and thus, for every type, are described boundary conditions, stationarity or transitivity, and the process of detirmining the final discretization of numerical model with convergence analysis. After the analysis is carried out, results are described in a more detailed manner, and also specific distributions of discplacements, stresses and temperatures are shown.
