Development of human
dummy as well as human body finite element (FE) models is closely related to
this activity. We have been using available
human body/dummy models
and have worked on extending the available models. One objective of our work is
to generate data about the dynamic properties of the human body tissue. This
data would include mechanical properties under impact conditions and their
variations with strain rate and the energy of the impact.
Facilities are in place
for static and dynamic testing on soft tissues, both tensile and compressive;
three-point/four point bending (static and
dynamic) on bones;
oblique/angular impact tests and the Split Hopkinson pressure bar are in place.
In order to examine tissue characterization
within four hours of
post mortem, it is desirable that the testing machines be taken to the hospital;
these compact and cost effective machines are designed in-house.
