Rules for evaluation and completion of the course
Lectures are not compulsory, attendance is registrated. Exercises are compulsory, and the attendance (80% at least) is checked and recorded. The absence (in justifiable cases) can be compensated by personal consultation with the lecturer and elaboration of individually assigned topics and exercises. Individual tasks must be finished and handed in the week course-unit credits are awarded at the latest
Aims
The course enables students to realize typical calculations of aircraft thin-walled structures in non-linear areas of loading.
