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.
Highlights
Developing efficient and highly precise methods for diagnosing products is a relevant science task: non-destructive testing allows defining timely defects of elements of important constructions
The Shock Pulse Method is widely applied [3], which is based on using the connection between natural frequencies of elastic oscillation and physical mechanical properties of materials and products
Let us look at the task on longitudinal oscillation of vector component of a magnetic field, the scalar an electrically conductive rod in a SMF
Summary
Developing efficient and highly precise methods for diagnosing products is a relevant science task: non-destructive testing allows defining timely defects of elements of important constructions. The Shock Pulse Method is widely applied [3], which is based on using the connection between natural frequencies of elastic oscillation and physical mechanical properties of materials and products. A way to define a rode defect by analyzing the spectrum of fundamental frequencies is offered. R. [5] offered a method allowing defining the location of a crack in a rod by natural frequencies of longitudinal oscillation in their article. An essentially new method is offered, which lets define experimentally frequencies of the normal mode of a rod’s longitudinal oscillation and determine the location of a crack
