sws: 2
lv-no.: 2173580
Notes

Molecular structure and morphology of polymers, temperature- and time dependency of mechanical behavior, viscoelasticity, time/temperature- superposition principle, yielding, crazing and fracture of polymers, failure criterions, impact and dynamic loading, corresponding principle, tough/brittle-transition, introduction to the principles of fiber reinforcement and multiple cracking in composites

learning objectives:

The students are prepared to

  • repeat the calculus on strength and design of engineering parts exposed to complex loadings,
  • estimate the influence of time and temperature on the strength of polymeric materials,
  • relate the strength of materials to their molecular structure, morphology and processing parameters and
  • derive failure mechanisms for homogenuous polymers and composite materials therefrom.


requirements:
basic knowledge in materials science (e.g. lecture materials science I and II)


workload:

The workload for the lecture Mechanics and Strengths of Polymers is 120 h per semester and consists of the presence during the lecture (28 h) as well as preparation and rework time at home (92 h).

Prerequisites

basic knowledge in materials science (e.g. lecture materials science I and II)

Bibliography

A literature list, specific documents and partial lecture notes shall be handed out during the lecture.
