Structure and Properties of Advanced Materials (FSI-TVN)

Academic year 2018/2019
Supervisor: prof. Mgr. Miroslav Černý, Ph.D.  
Supervising institute: ÚFI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The main aim lies in elucidation of unique microstructure of advanced materials as well as in understanding a physical nature of relationship between the microstructure and mechanical properties of such materials. The student also gains basic information about possibilities of application of these materials in the recent engineering practice.
Learning outcomes and competences:
The student gains basic information concerning structure, mechanical properties, and applications of advanced materials in recent engineering and technology.
Prerequisites:
Solid State Physics, Materials Science and Engineering.
Course contents:
Crystalline structure, microstructure, mechanical properties. Prediction of materials characteristics. Application of selected advanced materials in the engineering practice. Nanostructured materials - carbon fibers, nanolayers and nanotubes, bulk magnetic nanomaterials and ultra-fine grained materials. Shape-memory alloys - shape-memory effect and principles of mechatronic actuators. Composite materials - fiber- and particle-reinforced composites and laminates.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
The assessment of a student is made upon his performance in practice and quality of a discussion on topics selected at the colloquium (lecture notes allowed at preparation).
Controlled participation in lessons:
The presence of students at practice is obligatory and is monitored by a tutor. The way how to compensate missed practice lessons will be decided by a tutor depending on the range and content of the missed lessons.
