Modeling elastic properties of composites using asymptotic averaging method with imperfect interface
A. P. Sokolov, V. N. Shchetinin, M. Yu. Kozlov
The paper presents a modification of the asymptotic averaging method for solving the
elastic properties homogenization problem for composite materials, taking into account
the phases interface elasticity. The conditions of a soft imperfect interface are considered,
which allow a displacements jump on phases boundary. A literature review of methods
for the interface modeling in composite materials is presented. The finite element method
is used for the numerical implementation of an averaging method. A model of a surface
interface finite element is proposed. The numerical method of elastic properties averaging is adapted to the presence of a discontinuity in the displacement field. Application
boundaries of the soft imperfect interface are estimated in terms of interphase layer properties ranges. The problem of interface parameters identification by experimental data is
considered. Computational experiments are conducted for dispersed-reinforced and unidirectional composite with isotropic inclusion.
