Drop tests used for validation of FE models of human head for HIC assessment

Head injuries are the most often causes of death in traffic accidents. To develop better interiors of cars or new protective devices (e.g. helmets) there is a need to quantify the mean criteria of injury. Most of today used head injury criteria use an integral value of acceleration of the head during a certain time interval. The main drawback of these criteria is the fact, that they use only linear acceleration of the head. For better HIC assessment there is a need to use different measures, e.g. combination of translational and rotational acceleration or criteria based on strain energy. For these purposes complex FE models are used. To verify the behavior of these FE models, drop tests with different drop height are usually used. The paper presents results of drop tests used to validate FE models of human head. According to data obtained from accelerometers the HIC was computed and the critical height was determined.
