Aim: To introduce the students to the continuum mechanical principles for deriving linear constitutive equations for macroscopically homogeneous composite materials. Using this framework the students will be able to derive linear elastic (in general anisotropic) stiffness and compliance parameters for a broad class of linear elastic composite materials, and fibre reinforced plastics. Furthermore, a theoretical introduction is given to the non-linear mechanical behaviour of cementitious composite materials. Some theoretical tools for the description of this non-linear behaviour are introduced. Finally it is shown how this description of non-linear material behaviour can be introduced in structural calculations.
