[PPS21-P01] Fracture process inferred from fragment shape in impact disruption
3-min talk in an oral session
Keywords:impact, disruption, fragment shape, fracture process
We find that, if the distribution of the shape parameters, (b/a, c/a), is homogeneous, and there is no fragment at c?? < k, where k is a constant (0 < k < 1; in Fujiwara et al. (1978) k was ~ 0.2), the averages of the shape parameters, (0.7, 0.5) can be realized. Then, we discuss the fracture processes to represent the homogeneous distribution in the shape parameters. The expected dominant fracture process in impact fragmentation is reported.
