Intended learning outcomes

Material is an essential component of design. Working as an engineer, you will deal with various types of materials. Despite being simple in use, paper constitutes one of the most complex materials among those you encounter in your daily life. Paper can be easily tested mechanically and exhibits a whole range of behaviours during its end use. Therefore, studying paper mechanics is an excellent opportunity to train your skills in analysing various aspects of mechanical behaviour of material.

To start with, paper and paperboard are composite materials, which are produced by a continuous process at unprecedented speeds of up to 100 km/h by a complex but yet extremely cost-efficient process. Paper is inhomogeneous and anisotropic. In a number of applications, it is used beyond its elastic limit. The strength of paper is size dependent and is different in tension and compression. Furthermore, paper absorbs water, which changes its mechanical properties and dimensions.

In this course, you will be exposed to the intricate mechanics of paper through a number of case studies, in which we will investigate real problem and learn how to solve them.

At KTH, we have a world-leading expertise in Paper Mechanics and contributed to the book that will be used in the course. We will also use the expertise available at Innventia AB, a recognized research institute dealing with paper and paperboard related problems.

After the course, the students should be able to

  • describe and analyse important paper technology applications using a correct solid mechanics terminology,
  • relate the results from the most important methods for mechanical testing of paper and board to the appropriate solid mechanics terminology,
  • describe important aspects of the constitutive modelling of paper and board for anlyses of converting and end-use applications, and
  • demonstrate the benefits of mathematical modelling and numerical analyses in paper technology applications
