Course detail

Analysis of Machine-part Failures

FSI-GA0Acad. year: 2019/2020

In the introductory part of the course, students are familiarized with the fundamental mechanisms of production and operation degradation in metallic materials used in engineering. The knowledge obtained will enable students to determine limit states more accurately, to use materials more effectively and to give a qualified appraisal of failure causes. Students will also be made familiar with methods for determining the causes of defects in machine parts, using specific examples taken over from the literature and from the lecturer´s practical experience (e.g. automobile and aircraft technologies, power engineering facilities, pressure vessels, production machines, etc.). As an integral part of the course, additional information is provided on the most frequently used experimental techniques (chemical analyses, inclusive of microanalysis, metallography, and fractography).

Learning outcomes of the course unit

Students learn to regard materials as chemically and structurally heterogeneous systems, whose behaviour in real operation conditions is influenced exactly by these heterogeneities. The methodology used in seeking the causes of machine part failures will enable students to solve these problems in connection with the interplay of heterogeneous material, type of loading, and action of ambient environment.


The basic knowledge in the field of materials engineering on the level of introductory courses in Bachelor degree studies. In-depth knowledge of limit states, in particular the problems of testing mechanical properties and failure mechanisms. General orientation in the area of problems of strength calculations of machine parts.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline.

Assesment methods and criteria linked to learning outcomes

Students are awarded for the course-unit credit on the basis of their individually prepared presentation and subsequent discussion (examinee and their colleagues, lecturer) on the topic delivered. Students choose presentation topics from handbooks, workshop proceedings or journals (in English or German) provided for this purpose.

Language of instruction


Work placements

Not applicable.


The objective of the course is to make students familiar with problems of the degradation of materials and with methods for assessing the causes of machine part failures on such a level that they are able to solve the respective problem individually or in cooperation with specialized workplaces.

Specification of controlled education, way of implementation and compensation for absences

There are no practical exercises, the only way of assessment is the "defence" of an individually prepared presentation.
