A variational critical-state theory of friction
Mary Agajanian, Nadia Lapusta, Anna Pandolfi +1
Friction plays a fundamental role in many natural processes, including earthquakes, landslides, and volcanic eruptions. Earthquakes occur when highly compressed fault surfaces accu…
An optimal-transport finite-particle method for driven mass diffusion
Anna Pandolfi, Ignacio Romero, Michael Ortiz
We formulate a finite-particle method of mass transport that accounts for general mixed boundary conditions. The particle method couples a geometrically-exact treatment of advectio…
A numerical model of the human cornea accounting for the fiber-distributed collagen microstructure
Maria Laura De Bellis, Marcello Vasta, Alessio Gizzi +1
We present a fiber-distributed model of the reinforcing collagen of the human cornea. The model describes the basic connections between the components of the tissue by defining an…
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 comparative accuracy and convergence study of eigenerosion and phase-field models of fracture
Anna Pandolfi, Kerstin Weinberg, Michael Ortiz
We compare the accuracy, convergence rate and computational cost of eigenerosion (EE) and phase-field (PF) methods. For purposes of comparison, we specifically consider the standar…
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…
