摘要:
A glass article having an engineered stress profile. The central or core region of the glass is in compression and the surface or outer region of the glass is either under neutral stress or in compression. The outer surface region and the core region are separated by an intermediate region that is under tension. A flaw that penetrates the outer region in compression will propagate in the underlying tensile intermediate layer, but will not penetrate though the compressive core region of the glass. The compressive core region prevents flaws from penetrating through the thickness of the glass.
