Abstract
A simple multiscale analysis framework for heterogeneous solids based
on a computational homogenization technique is presented. The macroscopic strain
is linked kinematically to the boundary displacement of a circular or spherical representative volume which contains the microscopic information of the material. The
macroscopic stress is obtained from the energy principle between the macroscopic
scale and the microscopic scale. This new method is applied to several standard
examples to show its accuracy and consistency of the method proposed.
