Course abstract

Students will acquire knowledge on durability, stiffness and stability of materials for calculation of constructions a, develop engineering perception, supporting on the theory they study to put into practice the substantiation of optimal structural design of construction and machines.

Learning outcomes and their assessment

Knowledge - students comprehend the basic principles of engineering calculation on strength, stability and deformation of materials and constructions. Assessment – interactive tests and two classroom tests.
Skills - using the methods and modes of the strength of materials students are able to perform practical calculations on strength, stability and deformation of engineering constructions. Assessment – 2 lab works.
Competence - students are able to solve technical problems and perform independent calculation and construction work of engineering constructions design. Assessment – 3 homeworks

11. Theories of strength. (Lectures – 2h, practical work – 1h).

Part time extramural studies:

All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar

Requirements for awarding credit points

Course assessment with a mark is formed follows:
• all laboratory work must be completed (20%)
• all homework must be submitted and successfully graded (30%)
• all interactive tests must be submitted and successfully graded (20%)
• two classroom tests must be written and successfully graded (30%).

Description of the organization and tasks of students’ independent work

The problems for independent work are similar to the ones given during practice work. The problem starts with statement of initial parameters. To solve the problem, application of the skills obtained during practice is necessary.

Criteria for Evaluating Learning Outcomes

The test with a mark is formed as the weighted mean of the results of interactive tests, homeworks, lab works and classroom tests.
