This investigation concerns to the determination of the material properties
of nanoscale thermoelastic composites of an arbitrary anisotropy class with stochastically
distributed porosity. In order to take into account nanoscale level at the borders between
material and pores, the GurtinMurdoch model of surface stresses and the highly conduct- ing model
are used. Finite element package ANSYS was used to simulate representative volume and to calculate
the effective material properties. This approach is based on the theory of effective moduli of
composite mechanics, modeling of representative volumes and the finite element method. Here,
the contact boundaries between material and pores were covered by the surface membrane elastic and
thermal shell elements in order to take
the surface effects into account
