title: [Progress of study on biomechanical mechanisms of head impact injury].
abstract: This article reviews the researches on biomechanical mechanisms of head impact injury. Biomechanical factors that contribute to craniocerebral impact injury are discussed. The processes of injuries to skull and brain are described respectively. The contents include the static anatomic structure and dynamic properties of the skull, the changes of shear force and stress in skull fracture. The mechanisms of brain injury by linear movement and rotational movement as well as the relationship between skull injury and brain injury are described and analysed. Also the existing problems and the prospects for further research are brought forth.
