In Part I of this report are described and evaluated various mathematical constitutive equations proposed to model the mechanical behavior of fiber-reinforced composite materials having different compliances in tension and compression. Five different constitutive equations are described in detail and evaluated in the light of three criteria. In Part II of the report two entirely different micromechanistic approaches are developed to explain these observed differences in tensioncompression behavior the mean-fiber-angle approach originated by Tarnopolskii et al. and the elastically supported tie-barcolumn approach originated by Herrmann et al.
