Isogeometrická analýza a její použití v mechanice kontinua

Abstract

Táto práca sa zaoberá riešením úloh mechaniky kontinua Isogeometrickou metódou. Jedná sa o pomerne mladý postup, ktorý spája výhody presnej NURBS geometrie a robustnosť klasickej metódy konečných prvkov. Metódu sme v práci podrobne rozobrali a popísali na riešení rovinnej Poissonovej okrajovej úlohy. Isogeometrickú metódu sme implementovali v programe MatLab a jednotlivé algoritmy sme priložili k textu.

Thesis deals with solving the problems of continuum mechanics by method of Isogeometric analysis. This relatively young method combines the advantages of precise NURBS geometry and robustness of the classical finite element method. The method is described on procedure of solving a plane Poissons boundary value problem. Solver is implemented in MatLab and algorithms are attached to the text.
