High Order ADER Schemes for Continuum Mechanics

Autor: Saray Busto, Simone Chiocchetti, Michael Dumbser, Elena Gaburro, Ilya Peshkov

Publikováno v: Frontiers in Physics, Vol 8 (2020)

In this paper we first review the development of high order ADER finite volume and ADER discontinuous Galerkin schemes on fixed and moving meshes, since their introduction in 1999 by Toro et al. We show the modern variant of ADER based on a space-tim

On thermodynamically compatible finite volume schemes for continuum mechanics

Autor: Saray Busto, Michael Dumbser, Ilya Peshkov, Evgeniy Romenski

In this paper we present a new family of semi-discrete and fully-discrete finite volume schemes for overdetermined, hyperbolic and thermodynamically compatible PDE systems. In the following we will denote these methods as HTC schemes. In particular,

A unified model for thermally-activated fault weakening during nonlinear dynamic earthquake rupture and off-fault fracturing in 3D diffuse fault zones

Autor: Duo Li, Alice-Agnes Gabriel, Simone Chiocchetti, Maurizio Tavelli, Ilya Peshkov, Evgeniy Romenski, Michael Dumbser

Earthquake fault zones are more complex, both geometrically and rheologically, than an idealized infinitely thin plane embedded in linear elastic material. Field and laboratory measurements have revealed intense fault weakening induced by flash heati

Unified description of fluids and solids in Smoothed Particle Hydrodynamics

Autor: Ondřej Kincl, Ilya Peshkov, Michal Pavelka, Václav Klika

Publikováno v: Applied Mathematics and Computation. 439:127579

Smoothed Particle Hydrodynamics (SPH) methods are advantageous in simulations of fluids in domains with free boundary. Special SPH methods have also been developed to simulate solids. However, there are situations where the matter behaves partly as a

Two-phase hyperbolic model for porous media saturated with a viscous fluid and its application to wavefields simulation

Autor: Evgeniy Romenski, Galina Reshetova, Ilya Peshkov

We derive and study a new hyperbolic two-phase model of a porous deformable medium saturated by a viscous fluid. The governing equations of the model are derived in the framework of Symmetric Hyperbolic Thermodynamically Compatible (SHTC) systems and

Computational Model for Compressible Two-Phase Flow in Deformed Porous Medium

Autor: Evgeniy Romenski, Ilya Peshkov, Galina Reshetova

Publikováno v: Computational Science and Its Applications – ICCSA 2021 ISBN: 9783030866525
ICCSA (1)

A new three-phase model of compressible two-fluid flows in a deformed porous medium is presented. The derivation of the model is based on the application of the Symmetric Hyperbolic Thermodynamically Compatible (SHTC) systems theory to three-phase so

Simulation of non-Newtonian viscoplastic flows with a unified first order hyperbolic model and a structure-preserving semi-implicit scheme

Autor: Ilya Peshkov, Walter Boscheri, Michael Dumbser, Evgeniy Romenski, Simone Chiocchetti, Matteo Ioriatti

We discuss the applicability of a unified hyperbolic model for continuum fluid and solid mechanics to modeling non-Newtonian flows and in particular to modeling the stress-driven solid-fluid transformations in flows of viscoplastic fluids, also calle

A structure-preserving staggered semi-implicit finite volume scheme for continuum mechanics

Autor: Ilya Peshkov, Matteo Ioriatti, Michael Dumbser, Walter Boscheri, E. Romenski

We propose a new pressure-based structure-preserving (SP) and quasi asymptotic preserving (AP) staggered semi-implicit finite volume scheme for the unified first order hyperbolic formulation of continuum mechanics [1] , which goes back to the pioneer
