Abstract
For a better understanding of the mechanical properties of hardened cement paste the microstructure of the material is examined. Based on a three-dimensional computer-tomography a finite element mesh at the micrometer length scale is introduced. With respect to the finite element solution, homogenization techniques are used in order to calculate effective elastic material properties. To identify the inelastic material parameters of the constitutive equations, one has to solve an inverse problem. The identification is obtained by solving an optimization problem through a combination of the stochastic genetic algorithm and the deterministic LEVENBERG-MARQUARDT method. Thermo-mechanical coupling is introduced in order to include thermal loadings. With this approach, damage due to frost can be simulated numerically.
