Mechanical Properties and Microstructure of Materials
FSI-TMSAcad. year: 2011/2012
The course is devoted to the microstructure and mechanical properties of basic material kinds; metals, ceramics and polymers. The first part deals with basic principles of interatomic bonds in solids and defects in crystals. The second part contents the theory of elastic and plastic deformation, principles of fracture mechanics and physics of metals fracture. In the third part, micromechanisms of deformation and fracture of ceramics are explained in the relation to physical aspects of advanced technologies of their production. The fourth part deals with the deformation and fracture of individual types of polymers and describes differences between their basic mechanical properties. The course is supported by an extended text book, training examples and guidelines for laboratory experiments.
Learning outcomes of the course unit
Students get knowledge in microstructural reasons for different mechanical properties of metals, ceramics and polymers and, moreover, in advanced technologies improving their properties. They learn physical approaches to investigation of materials properties by solving working examples.
Basic knowledge of materials engineering, physics and mathematics are expected.

Planned learning activities and teaching methods
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
Assesment methods and criteria linked to learning outcomes
The examination is based on the test associated, when necessary, with an oral discussion of its results. A necessary condition is rather inedpendent solution of, at least, one of working examples during the training part of the course.
Language of instruction
The aim of the course is to present a self-contained overview of basic relations between the microstructure and mechanical properties of materials. An emphasise is given to the understanding of micromechanisms of deformation and fracture operating in fundamental classes of materials as metals, ceramics and polymers.
Specification of controlled education, way of implementation and compensation for absences
The presence in the training part of the course is obligatory and it is controlled by the teacher. The way of compansation of a missed subject matter depends on its extend and content.
