Measurement of Stress Waves Propagation in Percussive Drilling [PDF]

open access: yesSensors, 2021
This work describes the results of a test campaign aimed to measure the propagation of longitudinal, torsional, and flexural stress waves on a drill bit during percussive rock drilling. Although the stress wave propagation during percussive drilling has been extensively modeled and studied in the literature, its experimental characterization is poorly ...
