Complex stress-engineered frangible structures

A stress-engineered frangible structure, comprising:

• a plurality of interconnected discrete glass members comprising a first glass member and a second glass member each including at least one strengthened glass portion comprising a stress-engineered glass material, at least the second glass member comprising at least one weakened glass portion;
• and
• a bonding member connected between the first and second glass members, the bonding member configured to transmit a fracture force propagating from the first glass member to the second glass member with sufficient energy to cause the at least one weakened glass portion of the second glass member to fracture;
• wherein fracture of the at least one weakened glass portion of the second glass member changes functionality of the frangible structure from a first functional state to a second functional state different from the first functional state.

A method for producing a stress-engineered frangible structure, the method comprising:

• providing a plurality of discrete glass members each including at least one strengthened portion comprising a stress-engineered glass material;
• and
• interconnecting the plurality of discrete glass members such that each discrete glass member is connected by way of a bonding member to an adjacent one of the discrete glass members, wherein:
• each bonding member is configured to transfer first propagating fracture forces from the at least one strengthened portion of a first glass member to the at least one strengthened portion of an adjacent second glass member such that secondary propagating fracture forces are generated in the adjacent second glass member in response to the transferred first propagating fracture forces sufficient to cause fracture of at least one weakened glass portion of the adjacent second glass member;
• and
• fracture of the at least one weakened glass portion of the adjacent second glass member changes functionality of the frangible structure.
