    We consider a class of non-quasiconvex frame indifferent energy densities which includes Ogden-type energy densities for nematic elastomers. For the corresponding geometrically linear problem we provide an explicit minimizer ...
  • Mola, Andrea; Heltai, Luca; DeSimone, Antonio (SISSA, 2014-03)
    We present a model for ship hydrodynamics simulations currently under development at SISSA. The model employs potential flow theory and fully nonlinear free surface boundary conditions. The spatial discretization of the ...

    Bristle-bots are legged robots that can be easily made out of a toothbrush head and a small vibrating engine. Despite their simple appearance, the mechanism enabling them to propel themselves by exploiting friction with ...
  • DeSimone, Antonio; Gruenewald, Natalie; Otto, Felix (2006-07-26)
    We present a model which explains several experimental observations relating contact angle hysteresis with surface roughness. The model is based on the balance between released energy and dissipation, and it describes the ...

    We study self propelled stokesian robots composed of assemblies of balls, in dimen- sions 2 and 3, and prove that they are able to control their position and orientation. This is a result of controllability, and its proof ...

    Fluid membranes made out of lipid bilayers are the fundamental separation structure in eukaryotic cells. Many physiological processes rely on dramatic shape and topological changes (e.g. fusion, fission) of fluid membrane ...

    Smectic C elastomers are layered materials exhibiting a solid-like elastic response along the layer normal and a rubbery one in the plane. The set of strains minimizing the elastic energy contains a one-parameter family ...
  • Mola, Andrea; Heltai, Luca; DeSimone, Antonio (SISSA, 2012-03)
    We present an innovative numerical discretization of the equations of inviscid potential flow for the simulation of three dimensional unsteady and nonlinear water waves generated by a ship hull advancing in water. The ...
  • DeSimone, Antonio; Bianchi, B.; Heltai, Luca (2009-07-30)
    This report presents a brief discussion of the theoretical aspects and practical implementation of STRATOS . STRATOS is a 3D code for the simulation of hydrodynamic flows for incompressible fluids, in the presence of a ...
  • Dal Maso, Gianni; DeSimone, Antonio; Mora, Maria Giovanna; Morini, Massimiliano (2005)
    In this paper some new tools for the study of evolution problems in the framework of Young measures are introduced. A suitable notion of time-dependent system of generalized Young measures is defined, which allows to extend ...
  • DeSimone, Antonio; Heltai, Luca; Manigrasso, Cataldo (2009-07-30)
    The deal.II finite element library was originally designed to solve partial differential equations defined on one, two or three space dimensions, mostly via the Finite Element Method. In its versions prior to version 6.2, ...
