A method for determination of in-hole dynamic force-penetration data from two-point strain measurement on a percussive drill rod

The aim of the present investigation is to establish a testing method suited for determination of in-hole dynamic force-penetration data for non-uniform standard percussive drill rod-bit configurat ...
