"Practical meaning of the drilling method is concerned of structure surface layers up to the depth of about a few millimetres. As soon as the investigated object is non-comparably more sizeable than the drilled hole dimensions it is possible to suppose small gradients of the stress components to be in this mm-depth and a choice of the drill hole depth influences the sensitivity of these experiments - the deeper we drill the greater is the gauge response (to depth about hole diameter). Therefore the individual influences projected to the experiment results are possible to define only in the case of their external separation. At next can be concluded, that only two relatively simple experimental measurements of two displacements on the bar specimen are sufficient for identification of basic material constants - Young's modulus E and Poisson's ratio \u013E - by the here presented method."@en .
