Intended learning outcomes

The rapid development of new materials leads to a demand for more advanced descriptions of the mechanical behavior of different materials at different length scales. Furthermore, numerical tools, such as the finite element method, also enable the use of such complicated material (constitutive) models when solving mechanical problems. The course aims to provide the student both with theoretical and practical knowledge about a large number of constitutive models relevant for a variety of different materials.

After the course the student should be able to

  • apply three dimensional material models for anisotropic elasticity, non-mechanical strains, plasticity, viscoplasticity, creep, viscoelasticity, damage development in analytic estimates and in finite element calculations
  • judge the practical applicability of the presented material models.
  • understand the coupling between micro mechanical modelling and three dimensional material models.
  • by use of finite element calculations or in analytic estimates be able to determine the stiffness for laminates, particle composites and materials with micro cracks and materials with periodic microstructure.
  • estimate stresses and strain in inclusions.

Course main content

The practically most important material models for mechanical calculations are presented. Consequences for finite element calculations are discussed for every material model. The properties if the material models are as well analyzed by simplified analytic methods.
