Detail analysis of complex connection in the structure
Hokeš, Filip ; Hradil,, Petr (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to find and describe dependence between load carying capacity of a pin connection and a pin hole drilling. The dependence will be made in according to standard ČSN EN 1993-1-8, by theoretical solution and finally by finite element method in the ANSYS system. The second objective of the thesis is focused on a verification of load test results by numerical methods. Numerical solution will be made up in two analysis with different types of finite elements. The most fiiting model will be used as a basis for description of the relationship between capacity and diameter of drilling.

Variational sequences in mechanics on Grassmann fibrations
Urban, Zbyněk
Extension of the variational sequence theory in mechanics to the Grassmann fibrations (prolongations) of 1-dimensional submanifolds is presented. The coordinate expressions of classes of differential forms, entering the variational sequence, are determined for arbitrary second order forms. In particular, the meaning of classes as the well-known variational objects (Lagrangian, Euler-Lagrange form, Helmholtz-Sonin form) is pointed out. The correspondence with the variational theory of parameter-invariant problems on manifolds is discussed in terms of the theory of jets (slit tangent bundles) and contact elements.
