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…

A multiscale model of distributed fracture and permeability in solids in all-round compression
Maria Laura De Bellis, Gabriele Della Vecchia, Michael Ortiz +1
We present a microstructural model of permeability in fractured solids, where the fractures are described in terms of recursive families of parallel, equidistant cohesive faults. F…
