Flow behaviour and viscosity 2 - Flow and viscosity curves. - Model function for flow curves 4. Flow behaviour and viscosity 2 - Time-dependent behaviour of materials - Temperature-dependent behaviour of materials 5. Rotational test 2 6. Elastic behaviour and shear modulus 2 7. Viscoelastic behaviour 2 8. Creep test and Relaxation test 2 9. Oscillatory tests 2 - Amplitude sweep test - Frequency sweep test Lectures, introductory conversation, heuristic conversation, illustration, use of analogies and algorithms, conversation retaining and deepening knowledge conversation. Observations The lecture will be interactive, directing learning is facilitated by engaging of students in conversation episodes - to capture their attention, for updating of knowledge previous acquired and to systematization / fixing of new knowledges (OG and O1). It will track the formation of general competence: ability to analyze and synthesize; accumulation of basic general knowledge; proper use of terminology in physics and computer science in written and oral communication in English (OG and O1). It will cultivate a scientific environment based on values and quality (O4). Main bibliography: ppt presentations for each course (provided by the head of discipline).
