Experimental comparison of shear properties of FRP measured by ASTM methods
Ponížil, Tomáš ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
Přesné určení konstitutivních smykových závislostí napětí na deformacích je základem pro pochopení chování anizotropního kompozitního materiálu. Bylo vyvinuto mnoho zkoušek smykových vlastností kompozitních materiálu. Jelikož vyvolání čisté smykové napjatosti je složité, tento stav je vyvolán pouze některými z nich. V této práci je ověřeno použití systému Aramis k vyhodnocení průběhu smykového přetvoření a následnému výpočtu konstitutivních smykových vlastností při provedení jednoduché zkoušky ohybem krátkého nosníku. Tyto výsledky jsou dále porovnány se zkouškou podle Nicolae Iosipesca.

Damage tolerance analysis of wing to fuselage joint of L 410 NG airplane
Duchoň, Peter ; Mališ, Michal (referee) ; Augustin, Petr (advisor)
Master's thesis deals with the damage tolerance analysis of wing-to-fuselage joint of L 410 NG airplane. Thesis includes determination of the load distribution to the individual attachments of wing-to-fuselage joint, residual strength analysis and residual fatigue life analysis of the most loaded attachment lugs, calculation of fatigue crack growth curves in the attachment solids and inspection program proposal. This analysis was performed using FE model of the wing and central part of the fuselage and AFGROW software.

Tail units design of VUT 100 aircraft made out composite
Berka, Martin ; Cejpek, Jakub (referee) ; Mališ, Michal (advisor)
This Master´s thesis describes the design of composite horizontal tail of VUT 100 aircraft. Load calculation and selection of the critical load cases is performed. Internal structure of stabilizer and right elevator is designed. Construction materials are chosen and the structure of the composite materials is proposed. FEM models of stabilizer and the right elevator are created in MSC Patran system and consequently the strength test of the models for the selected load cases is executed using MSC Nastran software and COMPOST.

Fuselage and control system design of VUT 081 Kondor
Kalný, Jan ; Šplíchal, Jan (referee) ; Mališ, Michal (advisor)
This master’s thesis deals with VUT 081 Kondor composite fuselage design and control system layout design. Load computation and selection of critical load cases are made. Principal inner surfaces of the fuselage are designed with respect to basic ergonomic requirements of the crew. Construction materials are chosen and a layup of composite materials is performed. Fuselage FEM model is made in MSC Patran/Nastran system and the structure-strength analysis is given for chosen load cases.

Designe of a control system for powered sailplane SONG
Cejpek, Jakub ; Šplíchal, Jan (referee) ; Mališ, Michal (advisor)
The objective of this work is to adopt and further expand the type design of the SONG motor glider. The study will result in the basic aerodynamic calculation and the design of lateral control system including structural strength inspection of selected parts. Subsequently, the proposal will allow for further calculation to be made (of flight mechanics, wings strength or fuselage and empennage firmness) and for more specific constructional design of individual components of the glider.

Design of Composite Chassis for Formule Student
Gregor, Lukáš ; Šplíchal, Jan (referee) ; Mališ, Michal (advisor)
This bachelor thesis deals with structural design and manufacturing of Formula student chassis according the latest rules with primary aim to composite monocoque. In theoretic part is briefly described Formula student and the team. It shows actual used designs of chassis in competition and characteristics of composites and sandwich structures. In design section is described the design of the chassis due to safety, ergonomics and connections to other parts of the car. At the end is shown the manufacturing process of CFRP monocoque. The output of this thesis is made chassis of Dragon 8.
