A finite element model for hybrid III dummy's lower torso is presented. All details of the dummy's knee structure are carefully considered. In order to justify the finite element model, numerical results are made to compare with the experimental results from both knee impact test and knee slider impact test. It is found that the finite element results agree very well with their experimental counterparts.

A new foam material model has been developed incorporating both theoretical formulation for low-density high-hysteresis foam and test data. Detailed formulation is presented. The finite element analysis of the resilient bumper and the IP head impact are also discussed. A good correlation is concluded by comparing the results from the tests and the FEA simulations.
