The design of a novel four ligament instrumented knee element for pedestrian safety testing is described. Knee shear and bending tolerances from PMHS (Post Mortem Human Surrogate) testing in the literature and current pedestrian safety testing procedures are considered for comparative purposes. Validation at component level of individual textile ligaments is compared to reported biological data for ligaments tested in tension. Testing and validation of the knee element in shear and bending at quasi-static rates is presented. The knee element offers an instrumented lightweight biofidelic frangible kneeform which is able to predict failure in individual ligaments and measure knee bending and shear displacement.
