This can also be found in an earlier work, in which Moss (1966) showed that controlled-rate cyclic loads of low order can crush the granitic quartz, while static loads of the same value may fail to break a similar grain. He then simulated a fluvial transport system by subjecting the granitic quartz to rotation in a steel drum containing water.
