Summary

Low cycle tensile behavior of a SiC/SiC composite was studied at room temperature. The cyclic load values were selected above the proportional limit to study the damage evolution. The proportional limit, however, was found to be very much dependent on the loading history. Results showed that most of the damage forms in early stages and occurs primarily in the matrix. Whether or not a specimen reaches the crack saturation limit under cyclic loads appeared to be dependent on the magnitude of applied loads.
