【 摘 要 】

References(5)Cited-By(3)The effect of the rate of loading on the crushing behavior of a single particle was investigated by compression tests on spherical specimens of eight kinds of brittle materials under a wide range of loading rates from 10-1 to 109 N/s. It was found that the loading rate affects the crushing behavior of the single particle. A singularity of crushing behavior was also observed under impact loading of duration comparable to the natural period of the specimens. The crushing efficiency was especially at its maximum.
