  • Effective conductivity of isotropic composite with kapitza thermal resistanceEffective conductivity of isotropic composite with kapitza thermal resistance

    The paper presents the methods to compute the effective conductivity of composites with imperfect interfaces of Kapitza’s type. In this case, the temperature is discontinuous while the flux remaining continuous across the interface. First approach is based on the model of circle assemblage with thin coating. Second approach is based on the FFT s...

  • Second order homogenization of quasi-Periodic structuresSecond order homogenization of quasi-Periodic structures

    In this paper, we developed a homogenization procedure based on the combination of asymptotic expansions and a variational approach in order to construct the higher order macroscopic energy of a quasi-periodic heterogeneous medium. The main assumption used in this approach to describe the quasi-periodicity is that the properties of a point in the...

  • A generalisation to cohesive cracks evolution under effects of non-Uniform stress fieldA generalisation to cohesive cracks evolution under effects of non-Uniform stress field

    The present paper considers the problem of the nucleation and the propagation of a cohesive crack at the tip of a notch in two-dimensional elastic structures using Dugdale’s or Barenblatt’s cohesive force models where the stress field associated with a pure elastic response is assumed to be smooth and bounded, but nonuniform. Further it is suppo...
