The goal | The objective is gaining the advanced knowledge in the field of strength of materials, mechanics and micromechanics of solids, as well as understanding the factors which influence the load carrying capacity of structures exposed to different loading types. | |||
The outcome | The course contributes to development of independence of the doctoral student in the new study and working tasks, communication and critical dialog with the colleagues from different technical professions. | |||
