Aim:  Properties of materials can be considered functions of material structure and composition. This way of treating material properties naturally leads to mathematical modeling of material properties as functions of material structure. Such models are can be applied to establish a basic understanding of material behavior as well as develop new materials with tailored properties – including composite materials. It is the aim of the course to introduce the fundamentals in modeling of mechanical and physical properties of building materials, including stiffness, conductivity and short and long term strength. Furthermore, it is the aim to demonstrate how material modeling can be used in an integrated material and structural design approach.
Contents:  Basic theory for determination of properties of composite materials. Rheology – time dependent properties of materials. Linear and non-linear fracture mechanics – crack propagation in homogeneous and non-homogeneous materials. Influence of vapor and fluids on deformations of porous materials.

Integration of the above disciplines in the modeling of properties of building materials – stiffness, creep and relaxation, time dependent strength, moisture and temperature dependent deformations as well as conductivity and rheological properties. The models are exemplified in the case of frequently used building materials, concrete and wood.

Modeling of fracture mechanical properties for inhomogeneous materials, especially fiber reinforced cement and concrete. Through micro-mechanical analysis material composition is linked with fracture mechanical properties and it is demonstrated how fracture mechanics can be used in structural design making an integrated materials -structural design approach possible.
