Why is geogrid so difficult to model in FEA?

Geogrids are composed of polymers with complex geometries and non-linear constitutive behaviour. So, how should they best be represented in FEA models?Even with the correct constitutive models and input parameters, the outputs of FEA models containing geogrid can be disappointing. Geogrid performance is often under-predicted. Why is that and how can predictions be improved?All these questions and more will be answered in this webinar by a leading expert in the field.Learning outcomes:• Select suitable constitutive models for geogrid• Derive material model input parameters for geogrid• Describe the concept of mechanical stabilisation• Understand how to simulate mechanical stabilisation of granular fill in FEAWebinar Presenters: Dr. Andrew Lees - Geofem; Ahmed Gad, Product Sales Engineer - Bentley Systems.
