MAGNETIC FIELD STRENGTH DISTRIBUTION ABOVE STEEL PIPELINE HAVING LOCAL STRESS CONCENTRATION ZONES IN GEOMAGNETIC FIELD
(pp. 9-17)

Abstract. It is considered theoretical model of steel pipeline in geomagnetic field. This pipeline has local areas of exceeded stress-strain state of metal.Spatial components of magnetic field strength distribution above steel pipeline local stress concentration zones are investigated. Based on them the symbolic expressions to conditions providing separate detection of local stress concentration zones in close sequence of ones are obtained.

Keywords: remote magnetometric control, geomagnetic field, steel pipeline, depth of steel pipeline, stress concentration zone of metal, resolution threshold.
