“…The base model totally includes 60,000 nodes, 1000 materials, and 83,500 elements; solid elements were used to represent the spongy bone while the cortical bone was modeled using shell elements; there was a ligament connection between the bones, and sliding interfaces were defined in the contact area; the whole model had no mechanical joint [ 49 ]. Several simulations were performed to compare with the data of cadaveric test to validate impact responses of each body part [ 50 , 51 ]. The model was used in injury reconstruction and successfully reproduced multiple injuries of an occupant, such as bone fractures and ligament ruptures, but the internal organs in this model were fused to form continuum bodied with homogeneous material properties, which means that the internal organs are not modeled individually.…”

The crash test dummy, an important tool for car crash safety tests, is of great significance to explore the injury biomechanics of the occupants and improve the safety performance of the vehicle. The article mainly consists of four parts: brief introduction of injury mechanism, early experiments for obtaining biomechanical response (animal tests, cadaver tests, and volunteer tests), and development and validation of mechanical dummies and computational models. This study finds that the current crash test dummies are generally designed based on European and American, so they have limitations on the damage prediction of other regions. Further research in the crash test dummy needs the participation of various countries in order to develop a crash test dummy that meets the national conditions of each country. Simultaneously, it is necessary to develop dummies of vulnerable groups, such as the elderly dummy and obese people dummy.
