Numerical modelling
The structural response beyond the scope of the available standards and under extensive loading configurations can also be modelled in more detail using advanced numerical models. The Finite Element Method (FEM) is often applied using commercial software and in-house developed source code.
For specific problems like local instability, post-peak behaviour, or the use of a combination of materials, current provisions available in the standards may not be sufficient in adequately evaluating the structural behaviour and more detailed numerical analyses are recommended. CERG has experience applying commercial and self-developed software to model and assess the mechanical response of structures, structural elements, in applying both commercial software and self-developed software to model and assess the mechanical response of structures, structural elements and road infrastructure. Licences for the following commercial software are available to CERG staff.
- ABAQUS
- Comsol
- Diamonds
- TNO Diana
Moreover, CERG carries out research in the area of road geometric and and pavement design with a focus on the implementations of automated vehicles. To this end, several Finite Element software packages, empirical tools, and simulations software are employed. In addition, researchers at CERG perform road infrastructure design tests utilising driving simulator setups in collaboration with the Institute for Mobility (IMOB) of UHasselt.
