[Biomechanical mechanism of diffuse axonal injury].

As one type of primary brain injury, diffuse axonal injury (DAI) has specific traumatic mechanisms. The occurence of DAI is close to the loading property, loading manner, structural characteristics of skull, brain tissue and neck. This article demonstrated how the stress and strain varied in brain tissue effected by the load magnitude, load waveform, load frequency, load duration, linear acceleration, rotational acceleration, compounded linear/rotational acceleration, brain tissue, cerebral falx, cerebellar tentorium, skull and neck, and what are the relationships between these factors and the event of DAI.
