2021, International Journal of Rock Mechanics and Mining SciencesCitation Excerpt :The statistical analysis between the TBM performance and the acquired parameters was also presented. Indentation test, also known as indentation hardness test, punch test and punch penetration test,32,51–57 was originally intended to provide a direct method for estimating the normal load on disc cutters in rock engineering. It is one of the most powerful method to understand the rock fragmentation mechanism.58,59
