Flaw-Insensitive Ion-Exchanged Glass: I, Theoretical Aspects

摘要

Stable crack growth can be produced on residually stressed surfaces, provided that the residual-stress profile is carefully chosen. Once identified, these conditions will lead to strength- ening and an insensitivity of strength to the size of the initial surface flaw. Theoretical calculations are performed that involve choosing idealized forms of either the required tough- ness curve or the residual-stress profile.
