Mathematical Modeling and Micromechanics of Fiber-Reinforced Bimodulus Composite Materials.

Abstract

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 tension/compression behavior: the mean-fiber-angle approach originated by Tarnopol'skii et al. and the elastically supported tie-bar/column approach originated by Herrmann et al.
