摘要：
Fragmentation of small solid particles as a result of collision with a rigid barrier is considered. It is shown that the application of the Griffith energy approach to dynamic fracture is characterized by specific surface energy differing from its value determined from static tests. The existence of the threshold fragmentation velocity is established and the method for its prediction is proposed. The method for experimental estimation of the fracture incubation time is also proposed.
