Summary

Thin-walled cylinders of a woven [0/90] continuous fiber-reinforced ceramic composite are tested in combinations of tension, torsion and internal pressure in order to characterize the stress-strain response. Damage envelopes, defined as the loci of combined load states that bound the region of elastic behavior, have also been measured. Loading beyond any given elastic limit can cause both an expansion and a translation of the original damage surface according to the maximum effective stress. Within the damage envelope Young's and shear moduli are dependent on both load angle and position in stress-space. For several different load paths an ultimate effective strain of 0.6% has been observed. An empirical model is also investigated and results are in reasonable agreement with proportional loading cases; for non-proportional loading only trends are predicted.
