Abstract:

Fourth of four parts. The objective of this study was to modify the Global Human Body Models Consortium obesity models to improve their response relative to the obese postmortem human surrogates in a series of tabletop belt tests. This study found that submarining could be modeled by breaking boundary condition or large shear deformation in flesh; detaching connection between the pelvis and surrounding flesh could release the boundary condition and therefore allow for submarining; pulling hard with a denser mesh in the flesh could break the boundary between flesh and pelvis, therefore leading to submarining; large shear deformation can be realized through using SPG particle-to-particle bond failure criteria; tuned smooth particle Galerkin parameters worked well in the belt pull test simulation, recreating similar kinematics in the GHBMC obesity model to the PMHS; and the same set of tuned SPG parameter did not enable the GHBMC obesity model submarining in the rear seat sled test simulation.
