• TITLE: Non-Destructive Testing of Rods Using a Potential Component of a Magnetic Field

  AUTHORS: A. K. Tomilin, E. V. Prokopenko

  KEYWORDS: Elastic Oscillation; Electric Mechanical Systems; Non-Destructive Testing; A Magnetic Field

  JOURNAL NAME: World Journal of Mechanics, Vol.4 No.2, February 18, 2014

  ABSTRACT: An essentially new method for non-destructive testing of elastic electrically conductive rods using non-vortex electromagnetic induction is proved theoretically. An experimental technique for defining a location of a cross crack is offered.
