Course information

Content and learning outcomes

Course contents *

·         Phenomenological description of mechanical behaviour of different polymeric materials

·         Linear viscoelastic behaviour

·         Boltzmann superposition principle and how it is applied to different cases of loading /straining: constant stress, constant strain, constant strain rate and sinusoidal stress/strain.

·         Time-temperature superposition applied to different polymeric materials

·         The main transition (glass transition): phenomenology and molecular interpretation

·         Sub-glass transitions: phenomenology and molecular interpretation

·         Semi-crystalline polymers: phenomenology and molecular interpretation

Intended learning outcomes *

The students should after completed course understand and be able to analyse the mechanical behaviour of polymeric materials at low strain levels. This include the Boltzmann superposition principle, the time-temperature superposition, the generic time-modulus relationship for amorphous and semi-crystalline polymers, the temperature shift factors for different transitions (main transition and sub-glass transitions). Furthermore, basic knowledge about the molecular interpretation of mechanical relaxation processes should be known by the students.

Ethical approach *

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
