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.
