Abstract	Tema ovog diplomskog rada je računalna dinamika deformabilnih tijela s primjenom u dinamici sustava više tijela. Cilj rada je provesti računalnu analizu dinamičkog odziva sustava deformabilnih tijela korištenjem metode konačnih elemenata izvedenih teorijom velikih pomaka i metodom dinamike sustava više tijela koja uključuje reducirane modele pojedinih deformabilnih članova sustava. Analiza je izvršena numerički na primjeru mehanizma s tri grede pomoću metode konačnih elemenata u komercijalnog programskom paketu Abaqus i pomoću metode dinamike sustava više tijela u komercijalnom programskom paketu Adams. Rad je podijeljen na pet poglavlja i tri dodatka. U prvom, uvodnom poglavlju, ukratko je objašnjena problematika primijenjene dinamike s naglaskom na dinamiku deformabilnih sustava više tijela. U drugom poglavlju opisana je teorija vezana za računalnu dinamiku deformabilnih tijela. Dan je pregled i opis korištenih algoritama, uključujući formulaciju problema dinamike deformabilnih tijela i metode redukcije reda modela pojedinih članova sustava. U trećem poglavlju ukratko su opisani korišteni, komercijalno dostupni, programski paketi Abaqus i Adams. U četvrtom poglavlju provedena je numerička analiza dinamičkog odziva mehanizma s tri grede koje su modelirane kao deformabilne. Grede diskretizirane konačnim elementima korištene su u programskom paketu Abaqus te u programskom paketu Adams kao reducirani modeli. U petom poglavlju ovoga rada dan je kratak osvrt na problematiku primijenjene računalne dinamike te je izveden zaključak o dobivenim rezultatima računalne analize. U posljednja tri poglavlja, odnosno dodatka, ukratko je dan pregled osnovnih izraza mehanike kontinuuma, modeliranja prigušenja i frekvencijske analize.
Abstract (english)	The subject of this thesis is computer dynamics of deformable bodies with application in multibody dynamics. The aim of this work is to carry out computer analysis of dynamic response of deformable body system using a large displacement finite element method and multibody system method which includes reduced models of individual deformable body. Analysis was carried out numerically on example of three bar mechanism using finite element method in commercial software package Abaqus and using multibody dynamics method in commercial software package Adams. The work is divided into five chapters and three appendices. In the first, introductory chapter, issues of applied dynamics is briefly explained with a focus on flexible multibody dynamics. In the second chapter, theory regarding computer dynamics of flexible bodies is described. An overview and explanation of used algorithms is given, including formulation of flexible body dynamics problem and methods used to reduce model order of individual system members. The third section briefly describes used, commercially available, software packages Abaqus and Adams. In the fourth chapter numerical analysis of dynamic response of three bar mechanism is carried out. Bars modeled as flexible bodies and discretized with finite elements are used in software package Abaqus and as reduced models in software package Adams. In the fifth chapter of this paper a brief review is given together with the conclusion on the results of numerical analysis. In the last three chapters, appendices, an overview of fundamental expressions in continuum mechanics, modeling of damping and frequency analysis is given.
