Research Frontiers in Terminal Ballistics
Abstract
An overview of the engineering mechanics research needs in the field
of terminal ballistics is discussed. Two broad areas of terminal
ballistics are considered – armor/anti-armor engagements and small
arms fired at individual soldiers. A brief review of the physics
present during each of these terminal ballistic engagements is
presented, followed by a discussion of the general approach used by
Army researchers for studying and modeling impact events. The next
generation of technology being considered for the two broad areas is
described and the specific research needs are then presented.
Throughout the presentation, an emphasis will be placed on engineering
mechanics. A brief overview of the Army research infrastructure will
also be given. Finally, a short discussion of relevant terminal
ballistic research topics not covered in this seminar will be offered
for completeness.
Biosketch
Todd Bjerke received his B.S. degree in aerospace engineering in 1985
from the State University of New York at Buffalo. He worked for
several years at the Arnold Engineering and Development Center in
Tullahoma, Tennessee in the area of hypervelocity impact physics using
two-stage, light-gas gun launchers. He joined the US Army Ballistic
Research Laboratory (later to become a component of the Army Research
Laboratory) in 1988. He received an M.E. degree in mechanical
engineering from Johns Hopkins University in 1992, and later went on
to obtain a Ph.D. degree in mechanical engineering from the University
of Delaware in 2002. He has performed penetration mechanics research
in the applied areas of armor/anti-armor, wound ballistics, and
theater missile defense, and has authored or coauthored 45
publications. He is currently active in the development and
application of dynamic fracture mechanics for terminal ballistic
events.
