Course detail

FEM for Aerospace

FSI-OKPAcad. year: 2020/2021

The course brings practical view on the finite element method (FEM) and its use to evaluate structure stress and deformation. It focuses on the use of FEM during component design and check, and structural units of aircraft structures. Software system in use is MSC.Patran/Nastran/Dytran.
