Reliability and robustness

How do systems perform and withstand damage?

Components interact to shape system behaviour. We study how these interactions influence reliability and robustness. Our work connects material and connection behaviour to structures and networks, examining how redundancy, segmentation, and ductility influence failure and damage propagation.

From uncertain initial failure to the assessment of system response. Highlighted connections identify interactions of interest. Conceptual illustration.

Questions we study

How does local damage spread?

Experiments and mechanical models connect component failure, changing structural geometry, and subsequent impacts to the extent of collapse.

What makes a system robust?

We develop probabilistic representations and robustness measures that distinguish initial failure from the consequences of damage propagation.

How should performance be assessed?

Our work examines target reliabilities, robustness thresholds, and design checks under normal, accidental, and malicious actions.
