The Dependency of Composite Strength on Volume Fraction

Abstract

The dependency of composite strength under combined normal stress is experimentally determined as fiber content varies over the range 40% less than or equal to vf less than or equal to 75%. Failure predictions of the tensor polynomial criterion agree well with experimental data in stress space. The maximum strain criterion predicts a physically inadmissible failure envelope in stress space due to the assumed linear constitutive law. In strain space the maximum strain criterion agrees favorably with experimental observation.
