  • Mishuris, Gennady; Wrobel, M. (2009-10-26)
    This work deals with a stationary axisymmetrical heat transfer problem in a combined domain. This domain consists of half-space joined with a bounded cylinder. An important feature of the problem is the possible flux ...
  • Slepyan, Leonid I.; Movchan, Alexander B.; Mishuris, Gennady (2010-03-01)
    We consider some structures where the harmonic ‘feeding’ wave localized at the crack faces can force the crack to grow. First, we present some results related to a lattice with a high-contrast layer, where the wave speed ...
  • Linkov, A. M.; Mishuris, Gennady; Fradkin, L.; Dobroskok, A. (2007-07)
    In the current paper crack redirection due to a strategic placing of a heat source in the vicinity of a crack tip is studied. Analysis suggests that for PMMA and considered temperature range the only factor responsible for ...
  • Mughal, Adil; Weaire, Demis (2009-12-31)
    The elegant properties of conformal mappings, when applied to two-dimensional lattices, find interesting applications in two-dimensional foams and other cellular or close-packed structures. In particular, the two-dimensional ...
  • Vaz, M. Fátima; Cox, S. J.; Teixeira, P. I. C. (2011-11-01)
    In-plane deformation of foams was studied experimentally by subjecting bidisperse foams to cycles of traction and compression at a prescribed rate. Each foam contained bubbles of two sizes with given area ratio and one of ...
  • Cox, Simon; Celestini, F.; Raufaste, C.; Kirstetter, G. (2012-11-07)
    We investigate the interaction between an infinite cylinder and a free fluid-fluid interface governed only by its surface tension. We study the deformation of an initially flat interface when it is deformed by the presence ...
  • Mishuris, Gennady; Movchan, N. V. (2008)
    Steady-state moving Mode-III infinite interfacial crack along the perfect interface in a dissimilar strip is investigated. The crack position is not generally speaking symmetrical with respect to the strip surfaces. Both ...
  • Raufaste, Christophe; Marmottant, Phillippe; Cox, Simon; Graner, François (2010)
    We study the elasto-plastic behaviour of materials made of individual (discrete) objects, such as a liquid foam made of bubbles. The evolution of positions and mutual arrangements of individual objects is taken into account ...
  • Cox, Simon; Hutzler, Stefan; Weaire, Denis; Janiaud, Eric (2007-11)
    Forced drainage describes the procedure in which liquid is added to a column of foam at a constant flow rate. For sufficiently high flow rates this results in a convective bubble motion, the symmetry of which depends on ...
  • Movchan, Natasha; Movchan, Alexander; Mishuris, Gennady (2011-09-06)
    An interfacial crack is placed within a two-phase elastic strip subjected to an out-of-plane loading. In the unperturbed state, the crack propagates with a constant speed V along the interface. The Dirichlet boundary ...
  • Mishuris, Gennady; Movchan, Alexander B.; Slepyan, Leonid I. (2008-02-01)
    We consider a nontrivial anti-plane shear fracture problem for a double-crack configuration where the remote external load is applied to the extracted mass-spring chain and the displacement field is symmetric with respect ...
  • Mishuris, Gennady; Movchan, Alexander B.; Slepyan, Leonid I. (2008-05)
    The paper addresses a problem of partial fracture of a lattice by a propagating fault modelling a crack bridged by elastic fibres. It is assumed that the strength of bonds within the lattice alternates periodically, so ...
  • Mishuris, Gennady; Movchan, A. B.; Bigoni, D. (2012)
    Analysis of propagation of a fault driven by a steadily moving shearing force through a structural interface reveals a channeling effect for the energy release. This effect implies that a steady-state solution for propagation ...
  • Hutzler, Stefan; Saadatfar, M.; van der Net, Antje; Weaire, Denis; Cox, Simon (2008-06-20)
    The study of soap films spanning wire frames continues to provide insight into both static and dynamic properties of foams. Experiments show that sufficiently small triangular faces shrink spontaneously, with their area ...
  • Mughal, Adil; Laurson, Lasse; Durin, G.; Zapperi, Stefano (2010-02)
    We study the effect of long-range dipolar forces on the dynamics and morphology of domain walls in magnetic thin films by numerical simulations of the spin-1 random-field Ising model. By studying the size distribution of ...
  • Vaz, M. F.; Graner, François; Teixeira, P. I. T.; Cox, Simon (2009-07-20)
    We have performed Surface Evolver simulations of two-dimensional hexagonal bubble clusters consisting of a central bubble of area λ surrounded by s shells or layers of bubbles of unit area. Clusters of up to twenty layers ...
  • Wróbel, Michał; Mishuris, Gennady (2013-11)
    In the paper, a novel algorithm employing pseudo-spectral approach is developed for the PKN model of hydrofracturing. The respective solvers compute both the solution and its temporal derivative. In comparison with ...
  • Boulogne, Francois; Cox, Simon John (2011-04-12)
    We simulate quasistatic flows of an ideal two-dimensional monodisperse foam around different obstacles, both symmetric and asymmetric, in a channel. We record both pressure and network contributions to the drag and lift ...
  • Argatov, Ivan; Mishuris, Gennady (2011-09-06)
    A three-dimensional unilateral contact problem for articular cartilage layers is considered in the framework of the biphasic cartilage model. The articular cartilages bonded to subchondral bones are modeled as biphasic ...
  • Mishuris, Gennady; Piccolroaz, A.; Movchan, A. B. (2007-08)
    The paper addresses the problem of a semi-infinite plane crack along the interface between two isotropic half-spaces. Two methods of solution have been considered in the past: Lazarus and Leblond [1998a. Three-dimensional ...
