Threshold Fracture Energy for Differently Shaped Particles Impacting Halfspace (Erosion-Type Fracture)

摘要：

　　Energetic aspects of erosion fracture are studied. Threshold (minimal) energy needed for initiation of fracture caused by a particle impact is estimated using the incubation time criterion. The dependences of the fracture threshold energy on impact duration are calculated for two different shapes of the impacting particle: sphere and cylinder. The difference in the threshold energy behavior between these two cases is demonstrated and discussed.
