Abstract
U eksploataciji, konstrukcije su podvrgnute različitim vrstama opterećenja, među kojima je toplinsko opterećenje. Toplinsko opterećenje uzrokuje promjenu temperaturnog polja konstrukcije te se manifestira kroz pomake, odnosno deformacije i pojavu naprezanja u određenim uvjetima. Takva vrsta opterećenja se analizira termomehaničkom analizom koja može biti potpuno spregnuta termomehanička analiza ili sekvencijalno spregnuta termomehanička analiza. Uslijed toplinskog opterećenja, ne dolazi do trenutnog stacioniranja novog temperaturnog polja već postoji vrijeme u kojem se vrijednosti stacioniraju. Takve pojave nazivaju se tranzijentnim pojavama čije se vrijednosti računaju raznim metodama vremenske integracije. Ovaj rad se bazira na sekvencijalno spregnutoj metodi koja podrazumijeva pronalazak temperaturnog polja, a potom se promjena temperature implementira u matematički model. Oba modela, termalni i mehanički, analiziraju se i opisuju jednadžbama Metode konačnih elemenata, dok se tranzijentne pojave obuhvaćaju i računaju eksplicitnom metodom vremenske integracije.
Abstract (english)
Structures are subjected to a variety of loads during exploitation, including a heat load. The heat load generates a change in the structure's temperature field, which presents itself as displacements, or deformations, as well as the appearance of stress under particular conditions. Thermomechanical analysis, which can be fully coupled thermomechanical analysis or sequentially coupled thermomechanical analysis, is used to study this sort of stress. Due to the heat load, the current staticity of the new temperature field does not occur, but there is a time at which the values are stationed. These are known as transient phenomena, and their values can be determined using a variety of time integration methods. This thesis is based on a sequentially coupled method that entails first locating a temperature field, and then incorporating the temperature change into a mathematical model. Both models, thermal and mechanical, are analyzed and described by equations of Finite element methods, while transient phenomena are encompassed and calculated by explicit time integration method.
