Abstract
Raspodjela tlakova na tunici intimi vrlo je teško mjerljiva jer ovisi o velikom broju faktora kao što su dimenzije ulaza u aortu, brzina kojom krv dolazi uslijed rada srca, broja otkucaja srca itd. Iz tog razloga potrebno je numeričkom metodom kao što je FSI analiza ili analiza metodom konačnih elemenata, koju za rješavanje problema koristi programski paket Abaqus korišten u ovoj analizi, dobiti vremensko – prostornu raspodjelu naprezanja i pomaka unutar aorte.
Abstract (english)
The distribution of pressures on tunica intima is very difficult to measure, beacuse it depends on a large number of criteria such as area of entrance, speed of blood that depends on heart, the heart rate, etc. Therefore, it is necessary to use numerical method such as FSI analysis or finitel element method that is used by the Abaqus program package used in this analysis, to obtain the time – spatial distribution of stress and displacement inside the aorta. Based on the data obtained from the FSI analysis, same data were loaded into Abaqus and a time – space distribution was made. Hyperelastic, NeoHook material is given and the distribution of pressure is made as Analytical field related to single time frame. In this theiss period of one second is divided into 20 equal periods. Based on the simulation, the results are shown as deformed net of finite elements, and that model can be compared with results obtained by the FSI analysis in OpenFOAM. Visualization of that data are shown in Paraview. From the obtained displacement results over 20 time periods for critical points, a graph was made that shows the time dependence of displacement and stress for the same.
