Grain crushing in geoscience materials–Key issues on
The first issue in this theme is how to define a suitable index that can precisely and globally quantify the extent of grain crushing during loading, as shown in Fig. 3a. The second issue is how to observe the evolution of grain crushing and its effects on the grading, grain contacts, deformation, and dilatancy and strength, which are generally obtained from laboratory testing or simulated

Crusher Wikipedia
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

The tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.
