Course abstract

This course comprises discussion about modelling of behaviour of materials respectively their physical and mechanical properties, response of material to load regime, characterization of stress-strain relationship in distinctive phases of loading. Study of deformation relationships of an isotropic, orthotropic and anisotropic material, General Hooke’s law, and stiffness compliance of material as well. Viscoelastic properties of materials including creep development and stress relaxation; mechanics of layered materials as well as thermohygromechanics of layered material and stability of elements, elements on viscoelastic foundation. Also principles and methods of structural optimization are acquired.

Learning outcomes and their assessment

Knowledges about principles of mechanics of materials and structures, skills to use the principles of mehanics for structural design; competences to set up the problem and an appropriate model for research, to choose the research method and to evaluate the acquired results. Assessment depending on results of experiments and exam at the commision.
