Abstract

V magistrski nalogi so predstavljeni razvoj in rezultati optimizacije novih 2D avksetičnih struktur z uporabo genetskega algoritma in metode končnih elementov. Razvita je optimizacijska zanka, s katero se strukture generirajo, simulirajo in ocenijo. Osnovna celica se v strukturo zloži po vnaprej določenem vzorcu. Mehanski odziv struktur je določen z linearno elastičnimi simulacijami, pri čemer se kot obremenitev uporabi pomik. Ker vse generirane strukture ne izkazujejo avksetičnega obnašanja, se za ločevanje dobrih in slabih uporabi matematična ocena.

Secondary title: Development of new 2D auxetic structures using a genetic algorithm
Secondary abstract: The master’s thesis presents the development and results of the optimization of new 2D auxetic structures using genetic algorithm and the finite element method. An optimization loop was developed to generate, simulate and evaluate the structures. The unit cell is assembled into a structure following a predefined pattern. The mechanical response of the structure is determined through linear elastic simulations, with displacement used as the loading condition. Since not all generated structures exhibit auxetic behaviour, a mathematical expression is used to separate the good from bad ones.
