Abstract
Protection Engineering Consultants (PEC), in cooperation with PPG Industries,
Inc., is investigating the performance of a new glass technology for antiterrorism/
force protection (ATFP) applications. This new PPG glass product is
significantly stronger than typical fully tempered glass, which is advantageous in
impact, ballistic, and blast resistant window design. This paper compares the
performance of this new glass technology, known as Herculite® XP glazing, to
that of traditional (annealed and fully-tempered) glazing subjected to blast loads.
The performance of the Herculite® XP glazing is based on results from a series
of static tests and a large-scale blast test on eight windows. The results of the
static and dynamic tests are briefly discussed. A brief discussion is also included
on the use of a statistical fracture based glass strength model called the Glass
Failure Prediction Model (GFPM) that was used to develop Herculite® XP
resistance functions employed in single-degree-of-freedom (SDOF) blast
response models.
Keywords: glass technology, blast testing, window design, SDOF analysis.
1 Introduction
Protection Engineering Consultants (PEC) and PPG Industries, Inc. are
investigating the performance of Herculite® XP glass, a new glass technology
that is stronger than typical fully tempered (FT) glass, for anti-terrorism/force
protection (ATFP) applications. To evaluate the performance of Herculite® XP
glazing subjected to blast loads, a single large-scale blast test on eight specimens
was conducted at the Air Force Research Laboratory (AFRL) at Tyndall Air
