Fracture behavior of surface-modified ceramics

Technical Report ·
OSTI ID:5997467
The overall objective of this work is to understand crack growth on surfaces that are being acted on by macroscopic residual stresses. In the current year work has been performed in 3 areas: (1) fracture behavior of ion-exchanged glasses; (2) fracture of SiC-coated graphite; and (3) sub-critical crack growth in ion-exchanged glasses. The work in the first two of these areas will be complete by the end of the current funding year and the third project was initiated in September 1990.
