Abstract
There are multiple test methodologies currently in use to assess the performance of current and novel protective equipment and to investigate the thoracic injuries caused by blast overpressure. Among these methodologies, there is the mannequin for the assessment of blast incapacitation and lethality (MABIL), an instrumented human upper body surrogate that can be used to assess the performance of personal protective equipment. The objectives of the current study were first to develop and validate with experimental data a finite element (FE) model of MABIL for the purpose of investigating and predicting its response to blast overpressure. The second aim was to compare the DRDC MABIL FE model responses with a human FE torso model. The MABIL mannequin and the human torso numerical models consist of a simplified two-dimensional slice taken at the mid-sternum level, and subjected to different blast loadings. Experimental data on MABIL captured during field trials were used to validate the numerical models. In general, the numerical chest wall acceleration, velocity and the viscous criteria were higher than the experimental ones. However, the ratio between the numerical and the experimental chest wall velocity was the same across the range of blast loads studied.
