Magnetoelastic Effect Detection with the Usage of Eddy Current Tomography

Magnetoelastic Effect Detection with the Usage of Eddy Current Tomography

The possibility of application of the eddy current tomography setup to measure the small permeability variations caused by magnetoelastic effect was presented. A ferromagnetic steel sample was prepared for applying wall stresses and measured for 30 MPa stresses. The Finite Element Method (FEM) was u...
