Static Analysis of the Parts of the Textile Structures
Husáriková, Natália ; Gratza, Roman (referee) ; Kytýr, Jiří (advisor)
Bachelor thesis deals with elastic modulus determination by experimental measurements and comparison with the manufacturer's declared values. Own methodology for measuring membrane strip is proposed in this thesis. Thus determined values of elastic modulus are used in analysis models using ANSYS software. Calculated values of displacements are compared with the manually measured values of displacements during the experiment. Membrane strip with a hole is modeled in the same way.

Assessment of fracture risk for a langlauf ski made as a glass fibre reinforced sandwich
Láštic, Daniel ; Majer, Zdeněk (referee) ; Burša, Jiří (advisor)
The first part of bachelor’s thesis is devoted to basic theoretical knowledge about usage of sandwich theory of beams, which are made of different materials in the core and faces. This part includes brief description of composites (common car- rying component of sandwich structures) with emphasis put on the fibre compo- sites and laminates. A special characteristic of composites – orthotropy is men- tioned. The second part is focused on description of obtaining of elastic constants of materials used in the real cross-country ski by experiment, on stress calculation and fracture risk assessment in cross-country ski made as sandwich structure for the most adverse operational state. The solution is executed with the help of an- alytical formulas of mechanics of materials derived in this part. The problem is also solved using finite element method (FEM) employing ANSYS software.
