Asymptotic analysis of Mohr-Coulomb and Drucker-Prager soft thin layers
F. Lebon and S. Ronel-Idrissi

    This paper deals with the asymptotic analysis of Mohr-Coulomb and Drucker-Prager soft thin layers bonded with elastic solids. In the first part, a mathematical analysis shows how to obtain an interface law that replaces mechanically and geometrically the thin layer. This law is strongly non-linear and couples microscopic and macroscopic scales. In the second part of the paper, the microscopic terms are quantified numerically, and it is shown that they can be neglected.
Key Words
    asymptotic studies; elasto-plasticity; non-associated laws; interface laws; finite elements.
