Abstract: This report was written by the author under the Engineer Scientist Exchange Program in the US Army Research Laboratory (ARL) from April 2013 to September 2014. To understand the loading mechanics of the anthropomorphic test devices (ATDs) lower leg in the presence of the blast-mitigating floor mat, the Finite Element Analysis (FEA) was conducted in various loading conditions. Through the FEAs results, the pulse-duration dependency was indicated in the ATD lower-tibia peak load, and the dependency was confirmed though the loading experiment. The ATD lower-leg loading mechanics are discussed with regard to pulse duration.
