Davydova et alii, Frattura ed Integrità Strutturale, 42 (2017) 170-180; DOI: 10.3221/IGF-ESIS.42.18 176 fragmentation intensity can be characterized by the number of fragments per unit mass, m N , which is easy to determine for all types of loads and which varies with the specific strain energy as the power law, Fig. 10. Figure 7: Fragments photo for sieve size: a) 0.63 mm; b) 3 mm; c) 7mm; d) more than 15 mm. Figure 8: Circularity vs sieve size for three samples. a) b) c) d)
