Obravnava primerov statično obremenjenih nosilcev z upoštevanjem viskoelastičnosti

Bregar, Žiga (author), Slemenik Perše, Lidija (mentor)

V sklopu naloge obravnavamo polimer kot gradnik statično obremenjenih konstrukcij, ter pri tem upoštevamo viskoelastične lastnosti, ki jih izrazito izkazujejo polimeri. Poleg viskoelastičnosti v nalogi upoštevamo še vpliv okolice, ter kako le-ta vpliva na napetostno-deformacijsko stanje nekega nosilca. Rezultate analitičnih preračunov smo podkrepili z numeričnimi simulacijami ter ovrednotili smiselnost rabe polimerov kot konstrukcijskega materiala.

• Title: Examples of statically loaded beams taking into account viscoelasticity

Abstract

In this thesis, we aimed to evaluate a certain polymer as the main construction material of statically loaded structures, while also taking into account the viscoelastic properties, which are strongly exhibited by polymers. In addition to viscoelasticity, the thesis will also consider the influence of the environment and how it affects the stress-strain state of a beam. The results of analytical calculations were supported by numerical simulations and the use of polymers as a construction material was evaluated.
