AEM: Advances in the Experiment-Modeling Dialog
Minisymposium organized by
- J. Réthoré, INSA Lyon, France
- S. Roux, ENS Cachan, France
Validation calls for a comparison between numerical modelling and experiments. Huge progress has been made in numerical methods dedicated to failure and crack propagation, and simultaneously full field measurements are now mature techniques to analyze fracture. Model-experiment dialog refers to the key link to be established to provide the best out of both domains. Examples include (but are not limited to):
- Providing a metric between the results of both approaches, allowing for a quantitative and critical analysis of their consistency;
- revisiting modelling parameters (geometry, loading, constitutive law, ...) based on experimental observations;
- identifying parameters which may be difficult to access otherwise (e.g. fine description of a cohesive zone model);
- delineating the limitations of simplified modelling (e.g. continuum damage vs. micro-cracks);
- designing an optimized experiment with the appropriate discriminating/robustness compromise;
- controlling an experiment on difficult-to-measure quantities (e.g. stress intensity factors, or modal mixity).
