Course abstract

The study course introduces students to stress/deformation analysis of isotropic and anisotropic material under different working conditions. Non-linear elastic, plastic and viscose elastic material behaviour models are being considered, as well as stability and dynamic behaviour of structures, optimisation problems formulation and solving, effective use of materials properties.

Learning outcomes and their assessment

1. Knowledge about models for stress/strain state of materials; ability to introduce material mechanics into structural design, to define problems and critically assess the calculation results.
2. Student is able to choice of reasonable substantiate the calculation model and results credibility on the basis of the knowledge gained.
3. Assessment by results of one workshop, one homework and examination.

Requirements for awarding credit points

Credit test will be enrolled, if student is able to discuss on course problems and calculation results, to justify methods chosen.
It is required positive assessment of workshop presentation, homework and final test

Description of the organization and tasks of students’ independent work

Workshop with each student short presentation about one of course problems – solving and discussion. Homework (printed out) - optimisation task formulatin and solving. Examination in test mode about course topics.

Criteria for Evaluating Learning Outcomes

Student will have positive assessment of test, if at least 50% of calculation records are correct.
The home work and workshop presentation will be assessed basing on two criteria: 1) fulfilment of task formulated;
2) ability to discuss calculations and substantiate results
