摘      要：In this paper,a high-speed photography method combined with drop-weight test is used to study the dynamic cracking behavior of PVB （polyvinyl butyral） laminated glass subject to low-speed *** patterns,paths and velocities,derived from a series of dynamic photos,are thoroughly analyzed to explore the characteristics cracking *** addition,given the different the experimental conditions,*** crack velocities,cracking speed （including maximum speed and speed-time history curve） are examined and compared.
