Abstract : Report covers research activities of principal investigator in relation to above project. Effects of scale are carefully quantified for media with periodic microstructure in which the scale parameter is the unit cell site over the representative volume dimension. Failure surfaces are defined for idealized truss-like composites and their dependence on scale has been explored. Concepts developed have been subsequently applied to aluminum honeycombs. The technical part of the work is reported in four papers. The present final report includes the final presentation given at AFOSR on September 13, 1996 and other relevant information
