Summary |
---|
The subject deals with elementary theoretical and practical knowledge from region behavior of materials and constructional elements under elevated temperatures, when thermoelasticity, creep or relaxation is situated. There are discussed topics including the basis from physics of materials, testing of materials, life-time prediction, etc. |
Learning Outcomes of the Course Unit |
---|
To teach students the basic procedures for solving some technical problems of the continuum mechanics. To ensure understanding of such teaching problems. To learn our students to apply of theoretical knowledge in praxis. |
