Failure in industrial processes is often related to wear and can cause significant problems. It estimated that approximately 1–4% of the gross national product for an industrialized nation abrasive wear. This work aims numerically predict development full-scale mining applications harsh sub-arctic conditions. The purpose increase understanding optimize service life minimize costs In present pap...
