MIL-HDBK-1013/12
GLOSSARY
Annealed Glass: glass which has been subjected to a controlled
cooling process to reduce thermal residual stress to a
commercially acceptable level.
Aspect Ratio: the ratio between the largest opening dimension
and the smallest opening dimension.
Asymmetrical Construction:
see non-symmetrical.
Blast Parameters: the primary variables which characterize a
blast pressure wave (incident and reflected overpressure,
incident and reflected impulse), each calculated at a specific
point.
Bending Stress: a stress system that simultaneously imposes a
compressive component at one surface, graduating to an imposed
tensile component at the opposite surface of a glass section.
Bite: in building construction, the dimension by which the frame
or flange of a gasket overlaps the edge of the glass or panel.
Block, Setting: a small piece of neoprene or other suitable and
compatible material used to position the glass in the frame.
Building Codes:
documents which prescribe acceptable building
practices.
Channel: a three-sided, U-shaped opening in a sash or frame to
receive a lite or panel.
Channel Depth: the distance from the bottom of the channel to
the top of the stop, or distance from sight line to base of
channel.
Chemically Strengthened: glass that has been ion-exchanged to
produce a compressive stress layer at the treated surface.
Cube Root Scaling: the concept of representing a bomb by scaled
distance varying inversely as the cube root of explosive weight.
Cube root scaling is the analytic basis for most blast wave
calculations.
