Structural Mechanics (3rd year)

Note that I'm slightly updating the data each year. The data for previous year is kept for your reference and is gradually replaced by a new one.

Presentations contain only graphical materials without full explanation. For full-text reference please refer to books recommended at the end of each presentation. Files are generated by PowerPoint2003. Presentations which include external files such as video fragments are packed into zip archives.
