Abstract
Cilj ovog diplomskog rada je numerička analiza i optimizacija geometrije koronarnog stenta za zadani materijal u radnim uvjetima. Rad kroz deset poglavlja objašnjava medicinsku pozadinu problema, bavi se teorijskim razmatranjima vezanima uz mehaniku čvrstog tijela te na kraju opisuje postupak modeliranja geometrije koronarnog stenta, njegovu analizu te optimizaciju geometrije. Dvije početne geometrije, nastale po uzoru na stvarne geometrije koronarnih stentova kreirane su pomoću programa za 3D modeliranje SolidWorks. Nakon toga, izdvojen je simetričan segment geometrije koji se uvozi u programski paket ABAQUS u kojem je odrađena numerička analiza metodom konačnih elemenata. Za obje inicijalne geometrije provedena je analiza naprezanja, a postupkom optimizacije oblika presjeka dobivene su konture optimalne geometrije. Optimalna geometrija za oba stenta modelirana je u SolidWorks-u te su rezultati provjereni ponovnim postupkom numeričke analize, ovaj puta za optimiziranu geometriju.
Abstract (english)
The goal of this thesis is numerical analysis and structural optimization of the coronary stent for given material in working conditions. Through its ten chapters, paper gives the medical background of the problem, explains theoretical considerations related to solid state mechanics and describes the procedure of modeling, finite element analysis and structural optimization of the coronary stent geometry. Two of the initial geometries were modeled on the existing stent geometries and created in the 3D modeling software SolidWorks. Then, the symmetrical segment of the geometry was singled out and imported in ABAQUS for the FEM analysis. Stress analysis was conducted for both initial geometries and the contours of optimal geometry were obtained through te process of shape optimization. Optimized geometry for both stents was also modeled in SolidWorks. In the end, simulation was repeated, but this time for the optimized geometry.
