Local Intrinsic Dimensionality of Ground Motion Data for Early Detection of Catastrophic Slope Failure
Yuansan Liu, James Bailey, Antoinette Tordesillas
Local Intrinsic Dimensionality (LID) has shown strong potential for anomaly detection in high-dimensional data, including landslide failure detection in granular media, where early…
On local intrinsic dimensionality of deformation in complex materials
Shuo Zhou, Antoinette Tordesillas, Mehdi Pouragha +2
We propose a new metric called s-LID based on the concept of Local Intrinsic Dimensionality to identify and quantify hierarchies of kinematic patterns in heterogeneous media. s-LID…
Spatiotemporal slope stability analytics for failure estimation (SSSAFE): linking radar data to the fundamental dynamics of granular failure
Antoinette Tordesillas, Sanath Kahagalage, Lachlan Campbell +3
Impending catastrophic failure of granular earth slopes manifests distinct kinematic patterns in space and time. While risk assessments of slope failure hazards have routinely reli…
Interdependent evolution of robustness, force transmission and damage in a heterogeneous quasi-brittle granular material: from suppressed to cascading failure
Antoinette Tordesillas, Sanath Kahagalage, Charl Ras +2
A heterogeneous quasi-brittle granular material can withstand certain levels of internal damage before global failure. This robustness depends not just on the bond strengths but al…
Statistical Properties of a 2D Granular Material Subjected to Cyclic Shear
J. Zhang, T. S. Majmudar, A. Tordesillas +1
This work focuses on the evolution of structure and stress for an experimental system of 2D photoelastic particles that is subjected to multiple cycles of pure shear. Throughout th…
Hyperstaticity and loops in frictional granular packings
Antoinette Tordesillas, Edward Lam, Philip T. Metzger
The hyperstatic nature of granular packings of perfectly rigid disks is analyzed algebraically and through numerical simulation. The elementary loops of grains emerge as a fundamen…
