The present work documents the critical axisymmetric stress states to yield continuous fiber composites, as a function of the elastic properties and volume fractions of the components. In the results presented here, the surfaces correspond to yield of the entire matrix. Some other analyses have based surfaces on the initial matrix yield. The yield surfaces produced here are nearly elliptical and can be characterized by three quantities: the lengths of the major and minor axes and the orientation angle of the ellipse. Although yield surfaces of specific fiber composites have been reported previously, this study addresses axisymmetric yield behavior over a wide range of component properties and volume fractions, in an effort to provide useful yield design criteria. Where appropriate, comparison will be made to estimates of yield of fiber composites based on finite element and self-consistent approaches, as well as particulate composite models based on upper bound approaches in the limit of rigid spherical particles, spherical cavities, and elongated cavities.
