Sandwich panels analysis under compressive load using finite elements methods
Seman, Matúš ; Löffelmann, František (oponent) ; Mališ, Michal (vedoucí práce)
Bachelor thesis deals with possibilities of numerical modeling failure mechanism in sandwich panels using final element methods. The first part of the thesis presents theoretical introduction to requirements of sandwich structures and either mathematic formulation of constitutive relations. The purpose of the thesis was to set suitable approcahes of formulation instability problems with applying on laboratory samples. The analysis was done using nonlinear solvers in programes Patran/Nastran and the results have been properly evaluated with experimental work and analytical approach.

Conceptual design of training aircraft with electric propulsion
Seman, Matúš ; Zikmund, Pavel (oponent) ; Hlinka, Jiří (vedoucí práce)
This thesis is focused on conceptual design of electric powered training aircraft, using certification guidelines CS-LSA. Designing process of geometrical and aerodynamic characteristics is primary based on statistics of certificated aircrafts in this particular category. The following calculation of performance stabilities and flight performances is based on knowledge of aerodynamic polar. The calculation of the polar is also part of this thesis. The last part of the thesis consists of construction design of the front part of fuselage and engine static structural analysis of engine mounts.
