Learning outcomes
|
The course emphasis on the theoretical basis of the discussed concepts and derivation of basic relations and relations between concepts. In addition, students gain advanced knowledge in certain topics focusing on the use of related courses in the theoretical basis of studies and master's degree. Students will gain advanced knowledge of the following topics of: curved beams and frames, thick-walled cylindrical vessel, rotating discs, circular plate, approximate methods of solving strut, bending and buckling combination, analysis of spatial stress and reshaping, and the mathematical theory of elasticity and basics of plasticity theory. In lectures is emphasized the relations and mutual relationships between quantities. Emphasis is placed on engineering approach to solve issues and corresponds to the basic course Strength of Materials I, including the derivation of all basic relations.
The aim is to extend students' knowledge gained in the previous basic course. The course puts more emphasis on the theoretical basis of the concepts discussed and on the derivation of basic relationships and connections between concepts. In addition, students will gain advanced knowledge in some thematic areas: crooked bars and frames, thick-walled cylindrical vessels, rotating discs, circular plates, approximate methods of buckling, combination of bending and buckling, analysis of spatial stress and strain and mathematical theory of elasticity and fundamentals of plasticity theory. In the course the relations and relations between the variables are emphasized. Emphasis is placed on the engineering approach to solving problems corresponding to the basic subject of Elasticity and Strength I, including the derivation of all the basics. relationships.
