Abstract

Three sets of test results on cadaver knees have been reported in the literature. The existing legforms, dummies and mathematical models do not validate under all these three test conditions. A computational model such as THUMS is expected to validate under multiple boundary conditions. Evaluation of the FE model of knee in THUMS against multiple test conditions has been conducted. The FE model in THUMS has been reoriented to obtain the configuration used to evaluate knee impacts to pedestrians. The model has then been validated against the test conditions used by Kajzer et al. Strain limits are used to evaluate the injury process of knee in the simulation.The injury patterns predicted in simulations were confirmed by the autopsy results. Response of the knee FE model was also analysed for tests conducted by Kerrigan et al. For the covering abstract see ITRD E141807.
