A numerical scheme for two-scale phase-field models in porous media

Bastidas, Manuela; Sharmin, Sohely; Bringedal, Carina; Pop, Sorin (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] We consider the flow of two immiscible fluid phases in a porous medium. At the scale of pores, the two fluid phases are separated by interfaces that are transported by the flow. Furthermore, the surface tension at ...
Explicit expressions for elastic constants of osteoporotic lamellar tissue and damage assessment using Hashin failure criterion

Megías Díaz, Raquel; Belda González, Ricardo; Vercher Martínez, Ana; Giner Maravilla, Eugenio (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] In this work, we have derived explicit expressions to estimate the orthotropic elastic constants of lamellar tissue as a function of the porosity at tissue level (microporosity) and the bone mineral density. Our ...
On Total Reuse of Krylov Subspaces for an iterative FETI-solver in multirate integration

Seibold, Andreas; Rixen, Daniel; Fresno Zarza, Javier (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] In this work, we adapt a Total Reuse of Krylov Subspaces for usage in a GMRESsolver and apply it to nonlinear structural-dynamics examples. These examples are then solved by a multirate FETI-method, the nonlinear ...
Augmented fluid-structure interaction systems for viscoelastic pipelines and blood vessels

Bertaglia, Giulia (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] In this work, innovative 1D hyperbolic models able to predict the behavior of the fluid-structure interaction mechanism that underlies the dynamics of flows in different compliant ducts are presented. Starting from ...
Numerical investigation on a block preconditioning strategy to improve the computational efficiency of DFN models

Gazzola, Laura; Ferronato, Massimiliano; Berrone, Stefano; Pieraccini, Sandra; Scialò, Stefano (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] The simulation of underground flow across intricate fracture networks can be addressed by means of discrete fracture network models. The combination of such models with an optimization formulation allows for the use ...
