Effect of layer thickness on critical angle of additively manufactured lattice structures
Nosek, Jakub ; Vrána, Radek (referee) ; Vaverka, Ondřej (advisor)
Aim of this work is to describe the effect of a layer thickness on critical angel of a lattice structures manufactured by SLM technology. The effect of layer thickness was investigated on single struts and on lattice structures made from stainless steel 316L. Better geometrical accuracy could be obtained, if the smaller layer thickness is used. Less attached powder particles on downskins was also observed on lattice structures. Thanks to this thesis, it is possible to determine, if it is meaningful to decrease the layer thickness in order to improve manufacturability of lattice structures even with higher manufacturing time.

Industrial Building - Review of Selected Reinforced Concrete Parts
Weber, Jozef ; Zlámal, Martin (referee) ; Švaříčková, Ivana (advisor)
Bachelor’s thesis deals with reinforced concrete floor structure. It is a 3D frame, which is composed of bar elements oriented in the longitudinal and transverse direction. The work is done calculating mean longitudinal beam and also the middle of the cross beam. Furthermore, the calculated floor structure, which operates in both directions. For the calculation of inner strength used computer program SCIA ENGINEER 2013.0, which operates on the Finite Element Method - FEM. All elements have been designed for ultimate and serviceability limit state. Work contains textual part, inner strength, static calculations, drawings and used documents.

Static analysis of sports hall
Jedlička, Michal ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
This Bachelor´s thesis is about the static analysis of sports hall in Libina. I have used a program RFEM for making the model. The model was elaborated according to the provided project documentation and valid regulations ČSN EN. The aim of this work is to analyze the real construction and to point out to the formation of possible problems.

Analysis of thermal behavior focused on additive manufacturing of lattice structures from AlSi10Mg
Nosek, Jakub ; Dočekalová, Kateřina (referee) ; Paloušek, David (advisor)
Using Additive manufacturing it is possible to manufacture complicated components, that cannot be manufactured using conventional methods. The typical example is the lattice structure. Fabrication of these structures is complicated, and it is different from the fabrication of bulk parts. Using numerical simulation which can reflect process parameters it is possible to analyze the thermal behaviour of vertical and inclined struts fabrication. Results show that the diameter of struts influences weld track width. This influence is caused by preheating the powder material by previous scanning paths. The final geometry of inclined struts is made in more scanning layers. In this work influence of the start and endpoint of trajectory is described.
