Abstract

The aim of the current study was to develop a finite element model of the abdomen for impact as part of the GHBMC coordinated effort. The model development and its validation were performed in multiple steps, from the selection of numerical formulations using isolated organ models, to the meshing of the full region and its validation against experimental data. The model response was found to be stable in 10 simulation setups, and close to literature data for most. However, the results highlighted the need to take into account geometrical differences between the model and the test subjects from the literature in order to be able to perform relevant comparisons. A sensitivity to the model mass was also observed for some of the test setups.
