Defence & Security
Martec Limited has extensive experience
in analyzing the interactions between blasts and structures,
and also the channeling of blast energy in semi-constrained
environments. Assessing the type or extent of structural
damage or harm to people that can be expected in these
scenarios is essential in structural design and in
the handling of situations to minimize potential negative
consequences.
Through involved analyses using Martec’s custom
fluid dynamics codes, and industry standard finite
element analysis packages, a quick estimate of the
type and scope of damage can be determined in minimal
time with very little overhead cost. Attempting to
duplicate the wide-range of urban situations which
can be simulated would require prohibitively expensive
experiments. Through use of sophisticated numerical
modeling, the appropriate cases for experimental
testing can be selected quickly and with a high degree
of confidence.
