Crack Development in Concrete, Part 2: Modelling of Fracture Process
In a companion paper in this conference  an experimental study is presented that deals with measuring fracture properties and obtaining 3D images of the particle structure in heterogeneous materials as mortars and concrete. The fracture mechanisms observed in the tests are modelled with a 3D lattice model. The heterogeneity of the model is directly implemented from the 3D images obtained in a CT-scanner. With this method realistic crack patterns can be obtained.
