Homogenizing elastic properties of large digital rock images by combining CNN with hierarchical homogenization method
Rasool Ahmad, Mingliang Liu, Michael Ortiz +2
Determining effective elastic properties of rocks from their pore-scale digital images is a key goal of digital rock physics (DRP). Direct numerical simulation (DNS) of elastic beh…
An optimal-transport finite-particle method for mass diffusion
Anna Pandolfi, Laurent Stainier, Michael Ortiz
We formulate a class of velocity-free finite-particle methods for mass transport problems based on a time-discrete incremental variational principle that combines entropy and the c…
Mesh d-refinement: a data-based computational framework to account for complex material response
Sacha Wattel, Jean-François Molinari, Michael Ortiz +1
Model-free data-driven computational mechanics (DDCM) is a new paradigm for simulations in solid mechanics. The modeling step associated to the definition of a material constitutiv…
Computation of effective elastic moduli of rocks using hierarchical homogenization
Rasool Ahmad, Mingliang Liu, Michael Ortiz +2
This work focuses on computing the homogenized elastic properties of rocks from 3D micro-computed-tomography (micro-CT) scanned images. The accurate computation of homogenized prop…
Model-Free Data-Driven Viscoelasticity in the Frequency Domain
Hossein Salahshoor, Michael Ortiz
We develop a Data-Driven framework for the simulation of wave propagation in viscoelastic solids directly from dynamic testing material data, including data from Dynamic Mechanical…
Actions over Core-closed Knowledge Bases
Claudia Cauli, Magdalena Ortiz, Nir Piterman
We present new results on the application of semantic- and knowledge-based reasoning techniques to the analysis of cloud deployments. In particular, to the security of Infrastructu…
