|
AT-1 |
Introduction. Introduction to the course objectives. |
2 hours |
|
The objectives of the course: following the completion of theoretical lectures
on the design welded structures and participation in practical coursework
(such as solving problems analytically and numerically, preparing seminary
presentations, etc.), candidates become competent in the field of designing
welded structures and acquire relevant academic skills. Furthermore, students
are expected to develop creative abilities and master specific skills related
to identifying and analysing the loads and the stress state within welded
joints and structures. |
