Development of Research on Dynamic Mechanical Properies of Joints

The research on dynamic response of joints under impact load condition is of significance on safe and efficient operation of product such as automobile and space vehicle.This paper summarizes the actuality and development of dynamic mechanical property research of joints both on experiment and numerical calculation in recent years.It is pointed out that strain rate,temperature and structural factor etc.Rave significant influence on dynamic mechanical properties of joints.Current application of impact test technology of joints and dynamic failure criterion of joints are also introduced.
