Microstructural Investigation of Granular Soil Upon Drained Cyclic Loading

This study investigates the microstructural response of a sand subjected to drained cyclic triaxial loading. Triaxial tests are performed within an x-ray tomograph to obtain grain scale measurements such as grain kinematics and grain contact orientations. ...

Coupled micro-computed tomography and micromechanical experiment on the failure of discontinuous porphyry rock

Edward Carlo Giorgio Andò

Rock is a discontinuous, heterogeneous material with complex mechanical behaviour. The variable material properties create uncertainty in response to load, associated rock mass damage and communition. Traditional approaches in rock mechanics rely on labora ...

Deciphering necking in granular materials: Micromechanical insights into sand behavior during cycles of triaxial compression and extension

Edward Carlo Giorgio Andò

This study elucidates the fundamental governing mechanisms behind necking instability in granular materials, a phenomenon extensively documented in the literature yet lacking a clear explanation of its underlying causes. Our findings suggest that the pheno ...

AngioPy segmentation: An open-source, user-guided deep learning tool for coronary artery segmentation

Emmanuel Abbé, Ortal Yona Senouf, Thabodhan Mahendiran, Ntorina Thanou, Edward Carlo Giorgio Andò

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional c ...

Micromechanics of Sub-Critical Failure in a Porous Rock: Insights from Integrating Sound and X-Ray Vision

Edward Carlo Giorgio Andò

Failure in brittle, porous materials initiates when structural damage localizes along an emergent failure plane in a transition from stable crack growth to dynamic rupture. Due to the rapid nature of this critical transition, the precise micro-mechanisms i ...

Fabric evolution and strain localisation in inherently anisotropic specimens of anisometric particles (lentils) under triaxial compression

Edward Carlo Giorgio Andò

Inherent anisotropy is often observed in natural soils and other granular materials formed during gravity deposition. Fabric characterisation and evolution have been mainly studied using numerical simulations, given the difficulty of retrieving the contact ...

X-ray radiography 4D particle tracking of heavy spheres suspended in a turbulent jet

Edward Carlo Giorgio Andò

The suspension of a heavy sphere by an upward jet is a classical fluid mechanics experiment to demonstrate the fluid forces acting on an object. In the range of the parameter space where the sphere can be suspended, the dynamics can either be regular, i.e. ...

Microstructure of Crushable Expanded Clay Aggregates

Edward Carlo Giorgio Andò

The images show two different and complementary views of a mixture of Light Expanded Clay Aggregate (LECA) particles with size ranging between 0.25–1.0 mm. The upper-left is a SEM image showing a projected view of the particles, while the lower-left is a s ...

Lessons learned from matching 3D DEM and experiments at macro, meso and fabric scales for triaxial compression tests on lentils

Edward Carlo Giorgio Andò

A series of discrete element method (DEM) triaxial compression simulations on specimens of an anisometric granular material starting from distinct initial fabric anisotropy states are conducted and compared with physical experiments on lentils at different ...
