Rock crushing by punches at various velocities of load application

Author: J. Zawada

The paper is the continuation of the analysis on crushing mechanics foundations presented by the author in his previous works.

In the paper there is presented the experimental analysis of two domestic rocks crushing by flat punches at various load application velocities within the range of 0.005-1000 [mm/s].

The solution scheme based on limit state theory was shown.

The studies results were discussed: mechanical characteristics, limit pressures and crushing energy corresponding to different load parameters.

The cognitive and practical conclusions were formulated in the paper.
