Patankar et al. have recently evaluated thermal stress distribution in alumina fiber (PRD-166)/N51A glass and alumina/SnO{sub 2}/glass composites using models due to Hsueh et al. and Vedula et al. They concluded that these models predict compressive stresses at the SnO{sub 2}/glass interface which would adversely affect the toughness. In this paper, the authors discuss some of the errors involved in Ref. 1 as well as point out our results of stress distribution in this composite system.
