Abstract. Experimental and computational research has been conducted for conceptual design
of mine-resistant boots. In the experiment an explosive charge generated
a shock impact to a metal wedge supporting a steel
surrogate leg. The impact load received by the leg was
recorded via strain gauges. The effect of a number of
factors such as standoff distance, wedge-angle and energy absorbing materials
on the impact load was explored. It was found that
the impact load is sensitive to the standoff distance but
less sensitive to the change of the wedge angle. Use
of honeycomb materials may reduce the impact load significantly. A
Dyna3D finite element analysis was also performed. The modelling results
were in close agreement with the measured results thus demonstrating
the utility of the finite element method as a useful
tool in the design and development of mine-resistant boots.
