    A Numerical Tool for Periodic Heterogeneous Media: Application to Interface in Al/SiC Composites
    (ASM International, 1999) D. Dumont; Frédéric Lebon; Ahmed Ould Khaoua
    A wavelet-Galerkin method for periodic heterogeneous media is presented. The advantages are to remove the mesh and to make adaptivity easier. Numerical results are presented. A specific study of interfaces in a Al-SiC composite is given. [S0021-8936(00)00301-9]

    Transient response of thermoelastic bodies linked by a thin layer of low stiffness and high thermal resistivity
    (Elsevier BV, 2014) Christian Licht; Ahmed Ould Khaoua; Thibaut Weller
    We extend to the thermoelastic case the study [1] devoted to the dynamic response of a structure made of two linearly elastic bodies linked by a thin soft adhesive linearly elastic layer. Once again, a formulation in terms of an evolution equation in a Hilbert space of possible states with finite energy makes it possible to identify the asymptotic behavior, when some geometrical and thermomechanical parameters tend to their natural limits, as the response of two bodies linked by a thermomechanical constraint. The genuine thermomechanical coupling remains in the constraint law only for a specific relative behavior of the parameters.
