Summary

A model was developed to calculate the redistribution of internal stresses in a composite when the composite is subjected to a constant stress at a temperature where the phases would exhibit time-dependent deformation. The general case of a composite with linear viscoelastic constituents is addressed and predictions are presented for the particular case of an elastic fiber embedded in a matrix that behaves as a Burgers material under distortion and elastically under dilation. The implications of these findings are discussed in relation to the behavior of ceramic matrix composites.
