Learning outcomes of the course unit
The course Aircraft Materials makes students familiar with representative aircraft structural materials as well as with their optimal use. Students will be able to evaluate different material variants of aircraft structures according their strength, lifetime and damage tolerance.
Prerequisites
Basic knowledge of relations between composition, processing, structure and properties of structural materials. Basic terminology of physical metallurgy and material limit states.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
For the course-unit credit it is necessary to attend seminars and to meet requirements of three written tests. A final evaluation consists of tests results (30 %) and oral examination (70 %).
Aims
The aim of the course Aircraft Materials is to inform students of present state in the area of structural materials for aircraft structures and to provide them with methodical and objective knowledge.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is compulsory. In case of justified absence, the missed seminar may be compensated with an individual assignment. Continuous checking is made by means of written tests. In case of a failure, it is required to repeat the test.
