Abstract:V zaključnem delu obravnavamo statični odziv ravninskih konstrukcij s pomočjo metode končnih elementov. Za ravninsko napetostno stanje je izpeljan štirivozliščni izoparametrični končni element, ki ga uporabimo za razvoj lastne programske kode, s pomočjo katere lahko analiziramo linearne in nelinearne odzive konstrukcij. Najprej so teoretično predstavljene vse metode in količine, ki jih kasneje uporabimo pri razvoju algoritmov. Prav tako je predstavljeno teoretično ozadje nastanka nelinearnosti v numeričnih simulacijah. Osnovo za razvoj kode predstavlja formulacija linearnega odziva, ki je osnova za opis iteracijskih in inkrementalnih formulacij, s katerimi lahko opišemo različne nelinearnosti. Naloga torej predstavi celoten razvoj programa za analizo po metodi končnih elementov, s katerim je moč izvesti procesiranje in poprocesiranje linearnih in nelinearnih ravninskih analiz.

Title:Modelling and code development for static response analysis of geometrically nonlinear planar structures
Abstract:In the final thesis, we discuss the static response of planar structures with the help of the final element method. A four-node isoparametric finite element is derived for the plane stress state, which we use to develop our own software code, with the help of which we can analyse linear and nonlinear construction responses. First, we theoretically present all methods and quantities, which we use later in the development of algorithms. We also present the theoretical backgrounds of the emerge of nonlinearity in numeric simulations. The basis for the development of the code is the formulation of linear response, which is the basis for the description of iterative and incremental formulations, with which we can describe different nonlinearities. The thesis thus presents the entire development of the software for the analysis according to the final element method, with which we can perform processing and post-processing of linear and nonlinear planar analyses.
Keywords:FEM, Abaqus, plane stress, static response, geometric nonlinearity, material nonlinearity, Langrangian formulation
