A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members. One-way crack propagation is achieved by providing a weaker member region only on the downstream side of each inter-structure bond.

A method for strengthening an edge of a glass laminate including a glass core layer positioned between a first glass clad layer and a second glass clad layer may include forming a channel in the edge of the glass laminate. Sidewalls of the channel may be formed from the first glass clad layer and the second glass clad layer. Glass filler material having a filler coefficient of thermal expansion greater than a core coefficient of thermal expansion may be positioned in the channel. The glass filler material and the sidewalls of the channel may be fused to the second glass clad layer thereby forming an edge cap over the channel. The edge of the glass laminate is under compressive stress after the glass filler material is enclosed in the channel.
