Including stochastics in metamodel-based DEM model calibration

In calibration of model parameters for discrete element method (DEM) based models the focus lies on matching the mean key performance indicator (KPI) values from laboratory experiments to those from simulation results. However, due to the stochastic nature of granular processes experimental results can show large variances. To include...

Towards the Automation of Preliminary Bridge Designs with Parametric Design Software: Assessment and optimization of multiple steel-concrete bridge typologies

This thesis concerns research into the parametric modelling and optimization of steel-concrete bridge typologies typically found in the Netherlands, in order to further the automation of preliminary bridge designs. The research question posed is: "How can a parametric bridge design model be composed to fit into the <br/>overall road design...
