Abstract
This study has investigated the response of the Total Human Model for Safety (THUMS) lower extremity finite element model under blast loading. Response of the model was estimated in simulated underbody blast (UBB) loading using floorplate impact velocities of increasing severity. Correlation and analysis (CORA) ratings suggested a good match between numerical response and available experimental data. The model response was then investigated in an antipersonnel landmine explosion. The model was found stable in the nearfield blast and sensitive to the threat definition. The lower extremity injury was predicted when detonation occurred below the heel. The model predicted major injuries localized to the hindfoot and midfoot with minimal damage to the forefoot, consistent with the findings in the literature. The damage to the individual bones of the foot was measured in terms of percentage change in mass and element eroded.
