Modeling of nonlinear constitutive relations of woven ceramic composites

Conference · · Ceramic Engineering and Science Proceedings; (United States)
OSTI ID:5944540
;

The linear and nonlinear tensile behavior of SiC/SiC composites is examined. This analysis is based on the observed stress-strain behavior and damage evolution from a series of loading and unloading tensile tests. Stress distribution of the composite with transverse cracks in the transverse yarns is examined, and the nonlinearity of the composite stress-strain relation due to the presence of transverse cracks is predicted by application of a maximum failure strain criterion for the transverse yarn. 7 refs.
