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.
