Mechanical and Structural Contributions to Anisotropy in Granular Materials
Mehdi Pouragha, Gertraud Medicus, Selvarajah Premnath +1
Anisotropy in granular materials arises from both the internal fabric and the directionality of the stress state, yet separating these effects experimentally remains challenging. T…
A physics-informed deep neural network for surrogate modeling in classical elasto-plasticity
Mahdad Eghbalian, Mehdi Pouragha, Richard Wan
In this work, we present a deep neural network architecture that can efficiently approximate classical elasto-plastic constitutive relations. The network is enriched with crucial p…
Quasistatic kinetic avalanches and self-organized criticality in deviatorically loaded granular media
Jordi Baró, Mehdi Pouragha, Richard Wan +1
The behavior of granular media under quasi-static loading has recently been shown to attain a stable evolution state corresponding to a manifold in the space of micromechanical var…
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…
Multiscale Modeling of Elasto-Plasticity in Heterogeneous Geomaterials Based on Continuum Micromechanics
Mahdad Eghbalian, Mehdi Pouragha, Richard Wan
In this paper, we investigate some micromechanical aspects of elasto-plasticity in heterogeneous geomaterials. The aim is to upscale the elasto-plastic behavior for a representativ…
