Imposed correlation between random field and discrete particle placement

Original language description

In recent time it has be recognised that capturing the spatial variability of mechanical properties of heterogeneous materials is essential for a realistic estimation of uncertainties in probabilistic structural analyses. Several authors have successfully proposed random field concepts in combination with standard finite elements. Although some discrete element models such as the lattice discrete particle model (LDPM) already mimic microstructural effects associated with the heterogeneity of concrete very well, when compared to the continuum framework, there are still known reasons for introducing higher order spatial variability. One such key issue concerns the ability to capture the well-known statistical size effect associated with the physical meaning of an auto-correlation length in material property fields. The presented paper addresses the issue of imposing correlation between a particular structural discretisation (i.e. radius and placement of particles in a discrete framework) and the realization of a random field for spatially variable material properties. Authors present here a novel method for imposing correlation between the discrete particle placement and a governing random field and illustrate the important implications towards enhanced realism in the reliability based assessment of concrete fastening systems.
