What was the hole depth for hole drilling?
The hole depth was equal to half of the specimen thickness and the hole-drilling operation was continued up to the symmetry plane of the samples. The released strains, due to the hole-drilling of quasi-isotropic symmetrical samples in [0/± 45/90] S stacking sequence, are shown in Fig. 4.17.See all results for this questionWhat kind of bit is used to drill a borehole?The borehole is drilled by the pulverizing action of a reciprocating steel bit suspended from the drilling rig by a wire cable. As the bit strikes the bottom of the hole, the formation is crushed, creating cuttings which are removed by bailing.See all results for this questionWhat is the purpose of incremental hole drilling?Incremental-hole drilling is used to measure residual stresses varying through the thickness, by drilling in successive depth increments ( Reid, 2009 ).See all results for this question
What are the tools used in horizontal directional drilling?
The tools and techniques used in the horizontal directional drilling (HDD) process are an outgrowth of the oil well drilling industry.See all results for this questionThe Horizontal Directional Drilling Processenlarged hole. Pilot Hole Directional Drilling Pilot hole directional control is achieved by using a non-rotating drill string with an asymmetrical leading edge. The asymmetry of the leading edge creates a steering bias while the non-rotating aspect of the drill string allows the steering bias to be held in a specific position while drilling.

The calibration constants needed to evaluate the local residual stresses from the measured strain data are well established for these two extreme cases.
